小型化宽带背腔缝隙天线

Abstract：A wideband cavity-backed slot antenna operated in the ultra-high frequency (UHF) band is introduced. The antenna has a compact structure and low profile with the size ratio of the ground plane to the slot only 1.6:1. The measured impedance bandwidth of VSWR≤3 achieves 85.3%, covering a frequency range from 390 MHz to 970 MHz. The measured gain is about 5.5～7.5 dB.
