Abstract
In this paper, we proposed a internal antenna for Quad band for GSM/DCS/USPCS/WCDMA Handset. Antenna Structure is designed to PIFA type. Antenna planed two independence patterns to reduce the size for efficiency and used shoting pin and inverse seven_type slit. Also they miniaturized the antenna construction electronic length for duty. furthermore, they designed and producted the antena height for 5w and ground term for 40*80mm. It is because they have wondered the thickness of terminal. used of for reduce size efficiently. The radiation pattern characteristic of antenna is compared and analyzed E-plane and H-plane at 920MHz, 1800MHz.
본 논문에서는 GSM/DCS/USPCS/WCDMA 단말기에 사용할 수 있는 Quad 밴드 내장형 안테나를 제안하였다. 안테나 구조는 PIFA구조로 설계하였으며 크기를 효율적으로 줄이기 위해서 단락핀과 역 세븐형 슬릿을 사용하여 독립적인 두 개의 방사체로 설계하였으며 접힌 구조로 전기적 길이를 효율적으로 배분하여 소형화하였다. 또한, 단말기 두께를 고려해 안테나 높이를 5mm, 그라운드 조건도
