Abstract

For developing a beam shaping antenna, the circumference and the length of the vertical and horizontal elements of the Modified Transmission Line type Antenna(MTLA) are varied. The vertical radiation pattern of MTLA which has various shape was analyzed by the moment method in order to verify the beam tilt characteristics. From the analysis, it is confirmed that the condition of the maximum beam tilt is determined by the length of the vertical elements of the antenna. The antennal with the maximum beam tilt was designed and its input impedance and the radiation pattern was calculated theoretically and measured experimentally.

빔 성형 안테나를 개발하기 위해서 변형된 전송선로형 안테나(MTLA)의 둘레 및 수평, 수직 소자 길이를 가변한다. 빔 틸트 특성의 검증을 위해 각각의 변형된 형상을 갖는 MTLA에 대한 수직면 방사패턴을 모먼트법으로 해석한다. 해석 결과로부터 구현될 수 있는 최대 빔 틸트는 주로 수직 소자길이에따라 결정된다는 사실올 확 인하였다. 최대 빔 틸트를 갖는 안테나를 셜게하고 입력 임피던스 및 방사 특성을 이론적으로 계산하고 실험에 의하여 확인하였다.
