摘要

本文介绍了三种用于金属发射装置的宽带紧凑型天线设计。第一个天线采用四分之一波贴片设计，其中一个边缘与地短路。为了降低操作频率，设计了另外两个天线，使用增加有效电长度的沟槽和狭缝。第二天线采用沿天线长度方向的边缘弯曲凹槽设计，第三天线采用天线表面的狭缝设计。天线采用n型连接器馈电。三根天线有21.6倍%, 11.9% and 6.85% bandwidth for VSWR $\leq 2$ at the center frequency of 1.9, 1.42, and 1.24 GHz respectively. First antenna is fabricated with single block of stainless steel to survive under high shock, vibration and surface temperature of 1000 degree Celsius and its performance is measured.

Broadband Compact and Rugged Antenna Designs for Launcher Applications

In this paper, three designs of broadband compact antennas are presented for their application inside metallic launchers. The first antenna is designed using quarter-wave patch with one edge shorted to ground. To reduce frequency of operation, two more antennas are designed using grooves and slits with increased effective electrical length. Second antenna is designed using curved grooves at edges towards length of antenna and third antenna is designed using slits on the surface of the antenna. The Antennas are fed using N-type connector. The three antennas have 21.6%, 11.9% and 6.85% bandwidth for VSWR $\leq 2$ at the center frequency of 1.9, 1.42, and 1.24 GHz respectively. First antenna is fabricated with single block of stainless steel to survive under high shock, vibration and surface temperature of 1000 degree Celsius and its performance is measured.
