Abstract

In this paper, an E-patch antenna on the U-shaped ground plane is designed and experimental studied. In order to reduce to cross-polarization level and to enhance the gain of the microstrip patch antenna, a U-shaped ground plane is employed in the microstrip patch antenna. As a main radiator, an E-shaped patch is used to reduce the antenna size as small as possible. Also to enhance the bandwidth of the antenna, a substrate of the lowest permittivity of which thickness as thick as possible is used and a rectangular patch is overlaid on the air substrate of the E-shaped patch antenna. The radiation characteristics of the antenna are calculated by CST Microwave Studio 5.0 simulation software. Experimental results show that by increasing the height of the sidewall of the ground plane, the antenna gain is increased and the cross-polarization level is decreased.

본 논문에서는 U형 접지면 상의 E-패치 안테나를 설계하고 실험적으로 고찰한다. 교차편파를 줄이고 마이크로스트립 패치 안테나의 이득을 향상하기 위하여 U형 접지면 상에 마이크로스트립 패치 안테나를 설치한다. 주방사체로서, 가능한 안테나 크기를 줄이기 위하여 E형 패치를 사용한다. 또한 안테나의 대역폭을 향상시키기 위하여, 가능한 두꺼운 기판의 낮은 유전율이 사용되고 E형 패치 안테나의 공기층 위에 사각형 패치가 씌워진다. 안테나의 방사 특성은 CST 5.0 시뮬레이션 소프트웨어로 계산된다. 실험결과 접지면의 벽 높이를 증가할수록 안테나 교차편파가 감소하고 이득이 증가한다.
