MOBILE WIRELESS COMMUNICATIONS DEVICE WITH SPLIT ANTENNA FEED NETWORK AND RELATED METHODS

摘要

A device may include a housing, a wireless transceiver carried by the housing, and an antenna element carried by the housing and having first and second feeds, and a split antenna feed network carried by the housing and providing a phase shift between the first and second feeds. The split antenna feed network may include a first capacitor having a first terminal coupled to the first feed and a second terminal coupled to the wireless transceiver, a second capacitor having a first terminal coupled to the second feed and a second terminal, a first inductor having a first terminal coupled to the second terminal of the first capacitor and a second terminal coupled to the second terminal of the second capacitor, and a second inductor having a first terminal coupled to the second terminal of the second capacitor and a second terminal coupled to a voltage reference.
