Wireless terminals
First Claim
1. A wireless terminal includinga substrate having a ground plane thereon,RF components mounted on the substrate,a PIFA (Planar Inverted-F Antenna) having connections electrically coupled to the ground plane, andthe RF components characterised in thata notch antenna is provided in the substrate for receiving signals, andde-activating circuitry is provided for de-activating the notch antenna when the PIFA is being used for transmitting signals.

Abstract
A wireless terminal includes a housing (10) containing a substrate (12) having a ground plane, RF components mounted on the substrate, a PIFA (Planar Inverted-F Antenna) (16) carried by the substrate and coupled electrically to the RF components for transmitting and receiving signals and a notch antenna (14) in the substrate for receiving signals in a frequency band at least partially overlapping the transmission bandwidth of some of the signals transmitted by the PIFA. The notch antenna is de-activated when the PIFA (16) is being used for transmitting a signal lying within the said transmission bandwidth.
