도시 지역은 복잡한 인프라 환경으로 인해 심각한 다중 경로 효과를 겪고 있으며 이러한 지역에서는 섹터 안테나가 기지국 안테나로 널리 선택됩니다. 섹터 안테나 내에서 옴니셀 안테나는 안테나 사이의 낮은 수신 영역을 커버하기 위한 지원 안테나로 활용됩니다. 본 논문에서는 이러한 환경에서 옴니셀 안테나로 동작할 수 있는 경사 45° 이중편파 무지향성 안테나를 제안한다. 주파수 대역은 1920MHz ~ 2170MHz 범위의 IMT 대역을 포괄하며 지향성은 수평면에 집중됩니다. 안테나 구조는 기생 요소인 원통형 슬롯 안테나 내부에 배치된 여기 요소인 루프 슬롯 안테나 어레이로 구성됩니다. S-파라미터와 지향성 결과 모두에서 4dBi 이상의 이득과 1.5dB 미만의 이득 차이로 우수한 성능을 얻었습니다. 측정 결과도 시뮬레이션 결과와 잘 일치하며 최종 설계를 통해 제안한 안테나가 경사 ±45° 이중 편파 무지향성 안테나로 효과적으로 작동함을 확인했습니다.

Abstract: Urban area suffers severe multipath effects due to its complex infrastructure environment and sector antenna is a popular choice as a base station antenna in those areas. Within sector antennas, omni cell antenna is utilized as supporting antenna to cover low reception areas between them. This paper proposes a slant 45° dual polarized omnidirectional antenna to operate as the omni cell antenna in those environments. The frequency band covers the IMT band, ranging from 1920MHz to 2170MHz with directivity focusing in horizontal plane. The antenna structure consists of a loop slot antenna array as excitation element which is placed inside a cylindrical slot antenna as parasitic element. Good performance is achieved in both S-parameter and directivity results, with a gain of more than 4 dBi and a gain difference of less than 1.5dB. The measurement results also agree well with the simulation results and the final design confirms that the proposed antenna works effectively as a slant ±45 ° dual polarized omnidirectional antenna.
