Abstract

Bowtie shaped meander slot antenna with harmonic suppression is designed and demonstrated experimentally. A substrate with height of 0.508 mm and relative permittivity of 2.5 is used, and the fundamental resonant frequency is 5.536 GHz. With thin conductor line in the antenna, harmonic suppression characteristic is obtained, and return losses at the 2nd and 3rd harmonic frequencies are -0.56 dB and -1.9 dB, respectively. Also, bowtie shape is applied to the antenna design for bandwidth enhancement, and the resulting bandwidth is 3.7 %, which is about three times wider than the reported meander slot antenna with harmonic suppression$\^$[1],[2]/.

고조파 억압 특성을 갖는 보우타이 형태의 미앤더 슬롯 안테나를 설계, 제작 및 측정하였다. 비유전율 2.5 및 0.508 mm 의 높이를 지니는 기판을 사용하였으며, 공진주파수는 5.536 GHz 이다. 안테나 내부에 금속선로를 삽입하여 고조파 억압 특성을 얻어내었고, 그 결과 제 2차 및 3차 고조파에서의 반사손실은 각각 -0.56 dB 및-1.9 dB 였다. 또한, 안테나 설계시 보우타이 형태를 적용하여 대역폭 향상 효과를 얻을 수 있었으며, 그 결과기존의 고조파 억압 특성을 갖는 미앤더 슬롯 안테나$^{[1]}$,[2]/와 비교하여 3배 정도 향상된 3.7 % 의 대 역폭을 보였다..
