ABSTRACT:
A compact integrated antenna device is described which has two feed ports. The antenna device has a Y-shaped transmission plate spaced from a parallel grounded plate, and the feed ports are connected to the transmission plate at locations on the transmission plate which are on different branches of the Y-shape. The antenna device can be utilized in compact wireless communication handsets to provide diversity signals or act as a duplexer allowing the receive and transmit signals to be mutually isolated.
