Compact DVB-H Antenna With Broad Dual-Band Operation for PMP Applications

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 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 omnidirectional patterns and sufficient gain (average peak gain over 470-862 MHz: 0.9 dBi) for the portable media player (PMP) applications. The antenna is contact with a PMP case (ε
_r
= 3.2), which is used as a substrate for the size reduction and compact design.
