Abstract

The present invention provides a mobile phone antenna, which comprises an antenna ground plane, a radiating conducting plate, a feeding conducting strip, a shorting conducting strip, and a system ground plane. Using the antenna ground plane as a shielding metal wall, the present invention advantages itself of making the antenna and a shielding metal box easier to be integrated without a need for an isolation distance. The present invention thus makes the best use of the internal spacing of a mobile phone. This antenna is suitable for application as an embedded antenna for both folded-type and bar-type mobile phones. The operating bandwidth of this antenna can cover the required bandwidth for a Universal Mobile Telecommunication System operation.
