We proposed a new efficient and flexible FPGA design method for the PYNQ-Z2 platform. The CASPER firmware interface is developed based on the PYNQ-Z2, and the FPGA firmware programs are designed using the CASPER toolflow. We used the PYNQ system to create a TCP service for communication with the CASPER library to enable remote real-time interaction, configuration, program loading and data reading from the hardware platform. The performance of the implemented CASPER platform is verified by designing firmware programs for GPIO, software registers, FIR digital filters and related experiments. The implemented approach provides rich development resources for FPGA development, shortens development cycle, improves development efficiency, and greatly simplifies the FPGA firmware design flow through platform-independent hardware and software.

In this paper, a thin-layer frequency selective surface (FSS) with wideband tunability and incidence stability is presented. The proposed design is composed of square metallic patches array and grid separated from a thin dielectric substrate where the varactor diodes are placed symmetrically. Adjacent metallic patches are connected with opposite electrodes, so that all varactor diodes are reverse biased in parallel. The results show that continuous modulation in the range of 2.798 GHz to 6.896 GHz (84.5%) can be realized by tuning the external bias voltage. The unit cell dimension is only 0.065λ0, which ensures that it has excellent angular stability within 75 degrees incident angles. Besides, it has stable response on both vertical and parallel polarized wave owing to its symmetry.

An ultra-wideband (UWB) low profile phased array antenna based on tightly coupled dipole array (TCDA) is proposed. In particular, a gradient line balun is integrated into each cell and a dielectric wide angle impedance matching (WAIM) layer is used to improve the scanning performance of the array. Simulation results show that the antenna unit can achieve 9:1 frequency bandwidth (when the active VSWR<3.5) in infinite period environment. Both E- and H-plane can be scanned to 45°. A 10×10 finite-scale array is fabricated and measured in microwave anechoic chamber, a beam scan range of 45° was achieved for E- and H-plane, and the measured VSWR<3.0 within 9 octaves of bandwidth is achieved resorting to the phase optimization.

The bandwidth ratio increasing of spread spectrum (SS) communication limits the performance of wideband adaptive interference cancellation (WAIC) for strong wideband interference signal. To improve the interference cancellation radio (ICR), wideband interference signal is divided into subbands to reduce the computational bandwidth of the WAIC algorithm. In this paper, a method that fits the wideband interference signal by multi-tone signals is proposed to explicitly analyze the effect of the signal bandwidth on the cancellation system and quantitatively calculate the analytical solution of the ICR. Basing on the method proposed, the performance can be evaluated by the amplitude and phase difference between the received signals from the main antenna and the auxiliary antenna. Simulations and experiments are conducted to verify the theoretical analysis, and the results are consistent. Therefore, the analytical method proposed in this paper provides the design guidelines between the ICR requirement and subband bandwidth, which can reduce the complexity in the implementation of the WAIC system.

A quasi-constant phase shifter enabled by band-limited non-Foster circuits is proposed in this paper. The proposed circuit provides wide band phase shifting with phase mismatch < 2.7°, amplitude mismatch < 1 dB over 10 GHz bandwidth, while supporting flexible phase adjustability. The band-limited non-Foster circuit structure is presented by using two side transistors to compensate the effects of cross-coupled transistors in Linvill’s structure [1], which shows positive capacitance at low frequencies and negative capacitance at high frequencies. To analyze the stability of band-limited non-Foster circuits and guide design optimization, Impulse Response Function (IRF) method is proposed, which takes into account circuit frequency dependent effects, distinct from conventional methods.

This paper presents a method to predict the detection performance of the RFID antenna based on Monte Carlo analysis. The specific designed reader antenna and the typical tags are modeled for electromagnetic simulations. The random numbers are generated by the Monte Carlo method to define the positions and orientations of the arrayed tags. Then, the transmission coefficients related to the different positions and orientations are developed to calculate the misreading probability of the reader antenna under different transmitting power levels. Finally, a passageway-type detection system has been built up to compare with the simulation results. The results show that the method proposed in this paper can better indicate the detection performance of an RFID antenna and provide a new prediction way for the design and application of RFID antennas.

This paper presents a 77 GHz patch antenna array with cavity structure based on the process of MEMS techniques for millimeter-wave radar. The designed antenna consists of feed line network and radiating patch, which are the integral parts of the antenna. The bandwidth is effectively improved by loading the cavity structure on the quartz glass substrate through MEMS process. The simulation results confirmed that the proposed antenna array obtains a bandwidth of 4.2% (from 75.25 to 78.47 GHz), with a 10.7 dB max gain within the bandwidth. The proposed antenna array has advantages in gain and bandwidth, indicating a great potential in the field of the millimeter-wave radar antenna. In addition, quartz glass substrate with cavity structures provides a solution for relatively high radiation efficiency and gain due to its lower mass production cost and better electronic compatibility. Thus, the designed quartz glass-based patch antenna array can be batch fabricated at low cost, and is highly suitable for hybrid integration with 77GHz millimeter-wave radar chips, thereby improving the performance of millimeter-wave radar.

An ultra-wideband (UWB) combined antenna for high-power microwave (HPM) application is designed in this paper. Tapered-slot balun is adopted to enhance the power capacity. In order to realize the smooth impedance variation from the feeder to the free space and improve the radiation efficiency and percentage bandwidth (PBW), principles of exponential taper, triangular taper and Klopfenstein taper are analyzed. The results of combined antennas with three types of impedance tapered structures are compared. Also, the size of magnetic dipole is optimized by adjustable plate to improve the low-frequency performance. Finally, a high-power ultra-wideband (HP-UWB) combined antenna with length of 300 mm is designed and simulated. With excitation of the high-power bipolar pulse whose amplitude is 125 kV, width is 2.7 ns and center frequency is 268 MHz, the weighted radiation efficiency of the antenna is 82.6%, while PBW is 146.9%. The power capacity of the antenna can reach to 200 MW.

Acoustically actuated mechanical ME antennas based on MEMS technology have been demonstrated to be one of the most effective technologies to miniaturize antennas. In this work, a new high-gain ultra-compact magnetoelectric antenna design based on FBAR for Portable RF wireless communication is introduced. This ME antenna is driven by acoustic waves and its fabrication is mainly based on the MEMS standard process. Due to the strong magnetoelectric coupling effect of magnetoelectric composites and the acoustic wavelength being much shorter than the EM wavelength at the same frequency, a high antenna gain of -15.77 dBi is achieved at the frequency of 2446 MHz. The effective electromechanical coupling coefficient and phase quality factor of the fabricated device are calculated as 1.3% and 172, respectively. This high-gain ultra-compact ME antenna takes a step forward for FBAR-based ME antenna research.

In this paper, a simple millimeter wave three-dimensional (3D) printed Luneburg lens antenna is proposed. A novel printable spherical lens geometry is constructed by combining cubical-lattice-type and rod-type gradient index materials. The lens is fed by a horn whose aperture is square, which ensures that the radiation patterns of E- and H- planes of the feed is almost symmetrical. The radiation characteristics of the lens with varied polarizations and incident directions for excitations are studied. The dual polarization radiation beam generated by the lens antenna can scan in a wide range and has stable performance in a wide working band. In whole Ka-band, |S11| is lower than – 17.5 dB, that is the impedance bandwidth of wider than 40%. The promising radiation patterns with the dual polarization scanning in an angular range of ±60° are obtained.
