Abstract

In this paper, we studied characteristics of the bent antenna febricated on Flexible-PCB. Flexible-PCB consisting of a polyimide has dielectric constant 3.5, thickness 0.125 mm. Proposed antennas which operates at Bluetooth band are a rectangular loop antenna and a loop antenna with inverted-L type stub. We compared the input matching and radiation characteristics of the proposed antennas under eight kinds of bending conditions.

본 논문에서는 Flexible-PCB에 제작된 안테나를 구부렸을 때의 특성 변화를 살펴보았다. Polyimide로 이루어진 Flexible-PCB는 유전율 3.5, 두께 0.125 mm를 가진다. 제안된 안테나는 Bluetooth 대역을 만족하는 기본적인 장방형 루프 안테나와 입력부에 Inverted-L 형태의 스터브를 추가한 안테나이다. 제안된 두 가지 안테나 모델에 대하여 8가지 조건의 bending 변화를 통해 bending 정도에 따른 입력 정합 특성과 방사 형태를 비교하였다.
