A novel planar ultrawideband (UWB) antenna with dual notched bands is proposed and investigated in this paper due to that UWB system is easy to be interfered with the narrow-band signals. The antenna consists of a square radiating patch and a modified grounded plane. To realize dual band-notched characteristics, a T-shaped stub embedded in the square slot of the radiation patch and a pair of U-shaped slots in the ground plane is utilized. The simulation results indicate that the designed dual band-notched planar antenna shows a very wide bandwidth from 1.9 to 12.5 GHz defined by voltage standing wave ratio VSWR<2 except the bandwidth of WiMAX and WAVE for band notched, which minimized the potential interferences between the ultrawideband systems and the narrowband communication systems effectively.

A novel circularly-polarized (CP) antenna with Broadband for navigation applications is presented. A circular patch is used as radiator, which is fed by the Wilkinson power divider operating from 1.1 to 2.8GHz. The Wilkinson power divider is designed based on composite right/left handed transmission line (CRLH-TL). The size of the proposed antenna is 0.7λ0 × 0.7λ0 × 0.1λ0 (λ0 is the wavelength at center frequency in free space). The impedance bandwidth for VSWR<2 is 50.9% and the AR bandwidth for AR<3 is 48.57%. Good agreement between simulation and measurement over the desired bands is obtained.

A broadband dual circularly polarized U-slot patch antenna element is proposed. By using thick substrate and dual-feed U-slot, the operating bandwidth is broadened. Dual circular polarization is realized by a feeding branch-line coupler. The element and an active phased array composed of 6 elements are simulated. Simulation results show that the bandwidth of 9-dB return loss and 6-dB axial ratio within θ < 60° is over 14% for the element with an overall size of 0.36λ0 × 0.36λ0 × 0.09λ0 without any air gap, where λ0 is the free space wavelength at the center frequency of the operating band. Scanning range of the phased array covers ±60° with gain fluctuation below 6 dB and axial ratio less than 6 dB.

In this paper, a design of massive MIMO antenna array working at millimeter wave (mmW) band with compact size and high gain is attempted based on resonant cavity antenna (RCA). Specifically, a 4-port MIMO antenna array working at 28 GHz with element spacing of 0.7 λ is presented, which consists of two layers of substrates. The upper layer is a frequency selective surface, and the lower layer consists of 4 microstrip patches being the MIMO feeding forts. Thus, the gain of each MIMO port can be improved sharply by sharing the same resonator without the need of designing complex feeding networks. Each port of the MIMO antenna array can obtain a gain around 15.2 dBi with a compact size of 25 mm × 25 mm (2.3 λ×2.3 λ).
本文以谐振腔天线(RCA)为基础，尝试设计一种体积小、高增益的毫米波频段大规模MIMO天线阵列。具体而言，提出了一种工作在28 GHz、元件间距为0.7 λ的4端口MIMO天线阵列，该阵列由两层基板组成。上层是一个频率选择表面，下层由4个微带片组成，作为MIMO馈电堡垒。因此，每个MIMO端口的增益可以通过共享相同的谐振器而无需设计复杂的馈电网络来大幅提高。MIMO天线阵列的每个端口可以获得约15.2 dBi的增益，其紧凑尺寸为25 mm × 25 mm (2.3 λ×2.3 λ)。

This paper designs a radar waveform playback system used for real-time digital signal processing test. The system reads radar waveform data stored in a disk array, and transfers it to a real-time signal processing system. The timing sequence and speed of the waveform data played back is the same as when radar in target tracking operation. The system comprises a disk array server, which is used for data recording and storing, and two FPGA (Field Programming Gate Array) fiber boards, which is used for data playback and transmission. Firstly, data transmission from the server to the fiber boards is realized by DMA (Direct Memory Access) in PCI Express protocol. And the DMA control flow for the system is proposed. Secondly, the method of timing control according to radar working mode is proposed. Accurate timing control can be realized by FPGA. Thirdly, the problem of asynchronous data transmission between two fiber boards caused by incoherent clock is solved. We propose two synchronization methods based on software and hardware respectively, and analyze the application conditions of each method. This paper offers a reference for the implementation of waveform playback in a radar system, and can be helpful for the function test of the realtime digital signal processing system.

In this paper, four antennas (planar inverted-F type, PIFA) are separately incorporated into a square-shaped smart watch for GSM/GPS/LTE/WLAN applications. The overall dimensions of the proposed design are 40.8 mm × 40.8 mm × 5.4 mm, in which all the four antennas are printed on the four side walls of the smart watch. Here, the PIFA used for GSM band has occupied two side walls (right and back sides), while the PIFA for GPS band has used only one of the side wall (front side), and the two PIFAs for LTE and WLAN band are printed on the same side wall (left side). The simulated and measured results have shown that all desired operating bands are well below the 6-dB return loss threshold, and the isolations between antennas are also well below 10-dB.

In the switching process of Press Pack IGBT (PPI) device, the phenomenon of nonuniform current distribution happens which cause the different power dissipation on paralleled chips. The phenomenon would be caused by several reason like clamping force, the temperature, as well as the parasitic effects like the parasitic inductance of the emitter structure, the parasitic resistance of the gate connector and the deviation of the paralleled chips characteristic, etc. As the parasitic inductance of the emitter structure is one of the main reasons of the nonuniform current during switching period, the parasitic inductance are extracted from the package structure model in this paper, and the equivalent circuit of device are built to analyze the characteristics of transient current sharing.

A compact filtering antenna based on alternative J/K inverters and λ/4 resonators are synthesized and designed in this paper. Parallel coupled line sections, via-holes, as well as L-shape monopole antenna are integrated to be a filtering antenna, with the parallel coupled line sections as J inverters and via-holes as K inverters. The L-shape monopole antenna is considered as a radiating impedance, and its equivalent circuit is first extract to replace the last resonator of the bandpass filter for the size reduction. The impedance matching of the antenna can be achieved by adjusting the last inverter of the filtering antenna and no extra impedance matching network is needed here. Finally, a filtering antenna operating at 2.4 GHz is designed and fabricated. Both the simulated and the measured results show a good frequency selectivity as a bandpass filter, and high radiation efficiency in the operating band as an antenna.
