ELECTRONICALLY TUNABLE QUAD-BAND ANTENNAS FOR HANDSET APPLICATIONS

摘要

An electronically tunable quad band antenna includes a tunable high band antenna tuned by at least one varactor (130) associated therewith; the tunable high band antenna further includes a substrate (125), a patch element (1 10) on the substrate, at least one volt tunable varactor (130) associated with the patch element, a DC bias point (115) on the patch element, an RF input (120) on the patch element and a temperature sensor (105) associated with the hi h band pass antenna.
