Abstract

In this paper, ㄷ-type MSA for the QMSA structure is proposed. Transformed ㄷ-type MSA is stacked three dielectrics. ㄷ-type MSA structure was load upper & lower surface of the dielectric radiating patch and the ground turn-up left right capacity between parallel plates and radiating patch. Between the dielectric permittivity of the dielectric insert by 2.55 by varing the frequency was shifted. Designed ㄷ-type MSA sturcture of L1 was varied up to 1mm~22mm and frequency was shifted from 3.65GHz~3.84GHz. Also Designed ㄷ-type MSA was measured 1.95dBi maximum gain and bandwidth of 1.61 to 3.64%.

본 논문에서는 기존의 QMSA의 구조를 변형하여 용량을 장하한 변형된 'ㄷ'자형 MSA구조를 제안했다. 변형된 'ㄷ'자형 MSA구조는 3개의 유전체를 적층시켜 상 하부 유전체의 방사패치와 접지면을 접어 올린 좌 우측 평행평판과 방사패치 사이 용량을 장하하고, 상 하부 유전체 사이에 유전율 2.55인 유전체를 삽입하여 가변시킴으로써 주파수를 시프트 하였다. 설계된 'ㄷ'자형 MSA구조는 삽입된 유전체 길이 L1을 1mm~22mm까지 가변시켜 중심주파수가 3.65GHz~3.84GHz대에서 이동하였다. 또한 설계된 'ㄷ'자형 MSA는 최대이득 1.95dBi와 1.61%~3.64%의 대역폭을 고찰하였다.
