摘要：

A wideband wide-coverage H-plane horn array with vertical polarization is proposed. Due to its light weight and low profile, the designed array is suitable for applications in spectrum monitoring systems on moving platforms. The switched-beam symmetrical array consists of four identical short H-plane horns. Pattern deterioration occurring in a high-frequency range is solved by inserting two pins in each horn. The measured impedance bandwidth is almost 100% for VSWR < 2 owing to its fed structure with a thick-cylinder-loaded probe. The measured azimuth-plane beamwidth is about 90. over the entire frequency range from 860 to 2500 MHz. Moreover, the measured results with the corresponding simulated results are presented and discussed in this paper.
