Compact and contact quad-band (DVB-H UHF/L, WLAN 11a/b) antenna for PMP applications

Abstract

The quad-band antenna, which is composed of two compact dual-band antennas, is presented for potable media player (PMP) applications. The antenna for the broadcasting dual-band (DVB-H UHF; 470–862 MHz, L; 1452–1492 MHz) is composed of a planar inverted F-shaped antenna with an input matching circuit. The antenna for the communication dual-band (WLAN 11b; 2.4–2.5 GHz, 11a; 5.15–5.8 GHz) is composed of a folded dipole antenna with enhanced mutual coupling. The proposed antennas are contact with the PMP case (ɛr=3.2) which is used as a substrate for size reduction and compact design.
