Abstract
An apparatus and method using a front internal dual band television antenna or a pair of internal dual band antennas for a portable entertainment module having a housing and a display screen. A front spiral antenna is embedded in the housing around the periphery of the display screen and is tuned to compensate for the influence nearby components. A rear logo-periodic antenna is located inside the rear of the housing and is modified to have various environmental openings to fit around existing components, vents and structures in the housing. Any pair of different antenna architectures could be used.
