摘要

提出了一种基于有机液晶聚合物衬底的轻型多层14ghz天线阵列。天线结构包括一个两层的公司馈电网络，该网络部分嵌入，通过过孔连接，也称为“缝合”。首先，采用4×4微带贴片阵列作为单元阵列，对4×8天线阵列施加90°相位差时，观察到6.5°波束转向。拼接4×8天线阵列的波束宽度为3 dB，为12°，无相移时最大增益为15.4 dB，有相移时增益降至13 dB。其次，应用拼接概念构造了16×16天线。结果表明，3 dB波束宽度为6°，增益为16.8 dB。

A ‘stitched’ flexible light weight multilayer 16×16 antenna array on LCP

This paper presents a light weight multilayer 14 GHz antenna array on an organic LCP (Liquid Crystal Polymer) substrate. The antenna structure includes a two layer corporate feed network, which is partially embedded, connected with vias, otherwise known as ‘stitched’. First, using 4×4 microstrip patch arrays as the unit array, a 6.5° beam steer is observed when a 90° phase difference is applied to a 4×8 antenna array. The stitched 4×8 antenna array has a 3 dB beamwidth of 12° and a maximum gain of 15.4 dB with no phase shift, and the gain drops to 13 dB with a phase shift. Next, a 16×16 antenna has been constructed applying the stitching concept. The results show a 3 dB beamwidth of 6° and a 16.8 dB of gain.
