차량전화용 1.9 GHz On-Glass 안테나의 특성
Characteristics of 1.9 GHz On-Glass Antenna for Automobil Telephone
초록
1.9GHz On-Glass 안테나의 이론 및 실험적 연구를 수행하였다. 본 논문에서 설계된 On-Glass안테나의 구조는 페이징 코일에 의해 분리된 5/8
Theorectical and experimental studies of On-Glass antenna in the 1.9GHz bandare performed. In this paper, the structure of designed On-Glass antenna consists of a 5/8-wavelength upper segment and quarter-wavelength lower segment separated by phasing coil. On-Glass antenna may be resonated by the use of suitably spaced phasing coil in series with the antenna wire. This tuning structure leads to an improvement in antenna efficiency. And then, this can be very useful for installation where limited space like automobil is available. The analytical method is based on collocation method with pulse function. The results obtained from numerical method are presented and compared with an experimental evaluation. From this, the VSWR, gain, radiation pattern, and bandwidth of the On-Glass antenna are analyzed.
