Abstract

The purpose of this study is to design for MOB antenna attached on safety helmet using microstrip patch antenna. The patch antenna is fabricated in 0.2 mm FR-4 substrate with $64{\times}64mm$ size. The proposed antenna is based on a slot-ring design which cover Inmarsat (1.52 ~ 1.65 GHz) and GPS (1.575 GHz) frequency band. To obtain the optimized parameters, HFSS simulator is used, and antenna is designed by optimized parameters. After antenna was etched, SMA connector was attached to the microstrip feeding line and the result between antenna simulation and measurement was analyzed. Proposed antenna is satisfied the -10 dB bandwidth requirement while simultaneously covering the 1.53 ~ 1.65 GHz.

본 연구의 목적은 안전모에 장착하는 MOB용 마이크로스트립 패치 안테나를 설계하는 것이다. 패치 안테나는 $64{\times}64mm$ 크기의 기판 두께 0.2 mm FR-4기판에 제작되었으며, Inmarsat (1.52 ~ 1.65 GHz)과 GPS (1.575 GHz) 주파수 대역을 커버하도록 슬롯링 형태로 설계되었다. 안테나는 HFSS 프로그램을 사용하여 최적화된 파라미터를 도출하고, 이를 바탕으로 시뮬레이션 측정 결과 분석을 통해 설계되었다. 안테나는 식각 및 마이크로스트립 급전 방식으로 SMA 커넥터를 부착하여 제작되었고, 안테나의 설계치와 측정치를 비교 분석하였다. 제안된 안테나는 1.53 ~ 1.65 GHz 밴드를 커버함과 동시에 -10 dB 대역폭 조건도 만족하였다.
