A single-layer circularly polarized (CP) substrate integrated waveguide (SIW) horn antenna is proposed. The proposed antenna is the combination of a classic SIW horn antenna and a printed dipole on the same substrate. The distance between the phase centers of the classic SIW horn antenna and the printed dipole contributes to the phase difference between the two orthogonal polarizations. Unlike the traditional antenna array with identical elements, the model in this work is essentially an array consisting of two different elements. The CP generation mechanism of the proposed antenna is discussed from the array perspective and a design guideline is laid down. The CP principle is verified by the simulated and measured results of the proposed antenna. The measured results show that the proposed CP SIW antenna has a 10-dB impedance bandwidth of 8.1% ranging from 10.6 GHz to 11.5 GHz, and its 3-dB AR bandwidth is 4.8% covering 10.73 GHz to 11.26 GHz. The radiation pattern of the proposed antenna is end-fire with a beam parallel with its plane.

A circularly polarized antenna with high radiation efficiency is proposed in this paper, which is based on multilayer PCB design and suitable for 28GHz millimeter wave band. The proposed antenna element is composed of four groups of monopole antennas that distributed in symmetrical structure. Each group of monopole antenna includes a feeding structure, a primary radiation sheet and a parasitic radiation sheet. The four groups of monopole antennas are successively fed with equal amplitude and 90° phase difference, then form circularly polarized antenna. Integrated with feed network and coaxial cable-like structure, the proposed antenna can cover the bandwidth of 26.5~29.5GHz with VSWR<1.2, AR<1.5dB and average radiation efficiency higher than 90%.

In this paper, a semi-active limiter in the 6~18GHz frequency band is designed. The limiter adopts a two-stage cascade design. The front-stage limiter uses a silicon-based diode to ensure the power capacity of the entire circuit. The final-stage limiter uses a GaAs diode to increase isolation and ensure fast response speed. The miniaturized broadband coupler is optimized by simulation, and the broadband coupling function is realized in a smaller size. Finally, the power tolerance capability of the limiter is analyzed, and the thermal distribution of the diode is simulated by software.

This paper describes a hybrid method of particle swarm optimization (PSO) algorithm and genetic algorithm (GA) optimization to synthesize millimeter wave lens antennas with flattop radiation pattern. This hybrid algorithm is beneficial to enhance the optimization efficiency and avoid falling into the local optimum. The designed lens antenna (LA) has 30° flat top radiation pattern in both the E-plane and H-plane. The antenna is optimized automatically, and it would be convenient. The simulated result shows that the antenna meets the design requirements and has the maximum gain of 12.03dBi.

In this paper, a design scheme of a high power endurance RF receiving front-end is proposed. In this scheme, the wide line-width suspended strip line high pass filter on the first stage of the component forms multiple transmission zeros at the low end to realize a high suppression, high power endurance and low loss filter. At the second-stage, PIN tube high-power limiter realizes a high-power, low-loss limiter circuit by cascading an active limiter and a passive limiter. The working input port and the self-checking input port are easy to be installed in the same plane with the front-end antenna through the BMA and SMP blind insertion structure. The actual measurement results show that the receiving front end has the characteristics of high power endurance, low noise figure and low in-band fluctuation.

This paper discusses the development of a novel compact stacked patch antenna with circular polarization (CP) covering 34 to 38GHz. The proposed antenna can be supplied in amplitude and/or phase tracking sets of typical airborne electronic reconnaissance or surveillance systems for wideband direction finding (DF) applications. Due to the limited installation locations, the antenna design employs stacked design to effectively reduce aperture and extend frequency bandwidth. The final configuration is optimized by using FDTD based 3D electromagnetic analysis software with overall size Ø10mm×1.1mm (without coaxial connector). Simulation results demonstrate gain ranging from 6.8 to 7.8dBic, VSWR≤2, broadside axial ratio≤4dB and half-power beamwidth (HPBW) between 75° and 90° over the entire operational frequency band which fulfill all system requirements.

A transmission polarization converter is described that is based on frequency selective surface (FSS) to convert the incident linearly polarized wave to a circularly polarized one. This polarization converter consists of four layers and contains two different unit cells. The structure has helped in achieving desired nearly a high transparency to two orthogonal components of transmitted waves while providing nearly 90º phase difference, as required for the generation of circularly polarized fields. The polarization converter offers axial ratio of less than 3 dB over 76.8%, from 9.2 GHz to 20.7 GHz. In addition, its working frequency band can still cover the range of 9.7 GHz to 20.1 GHz when the incident angle increases to 20°. Theoretical analysis and results of numerical investigations related to the structure are presented.

This work describes a design of a printed Marchand balun from the perspective of its cavity counterpart. The cavity balun is first planarized and then folded to accommodate into a spiral antenna. The width of the proposed balun is reduced to alleviate the influence to the spiral radiator. A simple planar structure based on a one-layered microstrip substrate is exploited to realize the design of the circuit scheme. It may reduce the degree of difficulty of Marchand balun working in very high frequency domain and enhance the rate of en-products by PCB technology. Finally, experimental results of the designed balun integrated with a spiral antenna working from 0.8 GHz to 5 GHz are provided to demonstrate the appealing performance of the design.

Phased array feed is a advanced array receiving technology in the field of radio astronomy and microwave receivers. It is equivalent to a small array antenna evenly placed at the focal field of the radio telescope. Through the beamforming network at back stage, pattern synthesis, beam scanning and even continuous beam coverage can be realized. Time modulated array is a four-dimensional array antenna technology that adjusts the array pattern and phase through time series. Although this technology is mostly used in satellite communication and radar systems, it is similar to the analog beamforming network composed of phase shifter and attenuator in phased array feed. In this paper, based on the technology of time modulated array, it is applied to the analog beamforming technology of phased array feed, and the relevant simulation is carried out.

SIW multi-polarized cavity antennas have been widely concerned because of their simple structure. Main mode (TE10 mode) is mostly used in this type of antenna at present, however, the number of slots on cavity surface is limited, which leads to low gain of the cavity. Based on SIW transmission mode, multi-inputs with inverse phase is used to excite high-order mode. According to the field distribution in cavity, the direction and phase of the radiation electric field of each slot on the cavity surface are analyzed, and a method of polarization direction synthesis is analyzed theoretically. A SIW multi-polarized antenna based on TE220 mode is designed by this method, and the slot number of radiation cell is confirmed by discussing the influence of the number on the dispersion characteristics, transmission and radiation performances of the cavity. What’s more, the antenna gain is promoted by forming a 2×2 array. The measured results show that this array has good radiation performance with relative bandwidth of 10%, gain of 11.7dBi at 9.7GHz, and cross polarization ratio greater than 10dB, which verifies the effectiveness of the polarization synthesis method.
