A new type of dual-polarization and dual-frequency multilayer-stacked microstrip array antenna is introduced. The feeding mechanism of the element is the aperture coupling for one polarization and the direct feeding for the orthogonal polarization. The microstrip element exhibits a wideband of operation. A slot etched on driven patch is used to improve isolation performance of the proposed antenna...
A high-efficiency microstrip-fed angled-dipole antenna has been developed. The printed dipole with an integrated balun features a broad operating bandwidth. The simulation of the antenna show that 7.4–10.5GHz band with VSWR less than 2 is obtained, and gain is more than 4.8dB. With choosing the proper dipole arms angle and with a radome, we can get the widest E-plane and H-plane beamwidth. Comparing...
A novel microstrip slot antenna backed by a ground plane with a U-shaped feed is presented. Based on the simulation, its impedance bandwidth for VSWRs ≤ 2 covers the range of 5.3 to 18.5 GHz, whose relative bandwidth reaches 110.9%. In addition, the good gain performance is achieved. These features make it an attractive canditate for a compact portable terminal in the personal, mobile satellite and...
