摘要

在机载通信领域，迫切需要一种具有垂直极化全向辐射模式的低剖面小型化天线，尤其是在甚高频（Very High Frequency，VHF）频段和特高频（Ultra High Frequency，UHF）频段的低频段.针对这一需求，本文提出了一种有着低剖面、电小尺寸的圆柱腔天线.通过在圆柱腔内部引入短路柱和导电柱分别激励起TM

和TM

模，能够获得良好的垂直极化全向辐射模式.引入锥形套筒在改善输入阻抗的同时，有效降低TM

和TM

模的谐振频率，使两个模式的谐振频率工作在目标频段.另外，设计了4个状态的宽带匹配网络来进一步改善天线的阻抗匹配.本文提出的圆柱腔天线尺寸为

Abstract

In the field of airborne communications

there is an urgent need for a low-profile miniaturized antenna with vertically polarized omnidirectional radiation patterns

especially in VHF and UHF bands. To satisfy this requirement

a cylindrical cavity antenna with a low profile and electrically small size is proposed in this paper. By introducing two short-circuited columns and a conductive column into the cylindrical cavity to excite the TM

and TM

modes

respectively

good vertical polarization omnidirectional radiation patterns can be obtained. A tapered sleeve is introduced to improve the input impedance and effectively reduce the resonant frequencies of the TM

and TM

modes so that the resonant frequencies of the two modes can work in the target frequency band. Besides

a broadband matching network with four states is designed to further improve the impedance matching of the proposed antenna. The size of the proposed cylindrical cavity antenna is

The measured results show that the proposed cylindrical cavity antenna achieves 47.3% (105~170 MHz) and 52.3% (207~355 MHz) impedance bandwidth in the low-frequency band and high-frequency band (
