Abstract

A dual-band (UHF: 470-862 MHz, L: 1452-1492 MHz) digital video broadcasting-handheld (DVB-H) antenna is presented. The proposed antenna is composed of a planar inverted F-shape antenna (PIFA) with an input impedance matching circuit. The matching circuit improves antenna performance in the broad UHF bands (470-862 MHz: 63%). The proposed antenna has omni-directional patterns and sufficient gain (Ave. peak gain is about 1.70 dBi over 470-862 MHz) for the PMP applications. The antenna is contact with a PMP case (${\varepsilon}_r=3.2$) which is used as a substrate for the size reduction and compact design.

본 논문에서는 듀얼 밴드(UHF: 470-862 Mhz, L: 1452-1492 MHz) DVB-H 안테나를 제작하였다. 제안된 안테나는 입력 임피던스 매칭 회로를 이용한 평판형 역 F 안테나 (PIFA)로 구성되었다. 매칭 회로는 안테나의 UHF 대역(470-862 MHz: 63%) 성능을 향상시켰다. 제시된 안테나는 전방향적 특징을 보이고 PMP에 적용 가능한 충분한 이득(최대 이득이 470-860 MHz에서 1.70dBi)을 보인다. 안테나는 소형으로 제작 되었으며 크기를 줄이기 위해 유전체로써 사용되어진 PMP 케이스(${\varepsilon}_r\;=\;3.2$)에 부착되었다.
