Abstract

A broadband microstrip-fed slot antenna is proposed for UHF applications. Its measured impedance bandwidth reaches 85.3% for VSWRles3, covering the frequency range from 390 MHz to 970 MHz. Backed by a cavity, the antenna achieves 5.5-7.5 dBi gain and has a compact structure, with the dimension of only 0.48lambda1 times 0.30lambda1 times 0.13lambda1 (lambda1 is the longest wavelength in the operating bandwidth)

用于超高频波段应用的紧凑型宽带槽天线
提出了一种用于超高频应用的宽带微带馈电缝隙天线。VSWRles3的测量阻抗带宽达到85.3%,覆盖390 MHz ~ 970 MHz的频率范围。该天线以空腔为背,实现5.5-7.5 dBi增益,结构紧凑,尺寸仅为0.48lambda1 × 0.30lambda1 × 0.13lambda1 (lambda1为工作带宽中最长波长)。
