Abstract
A ferro-electric (FE) tunable antenna matching circuit is provided for a multi-band antenna. The tunable matching circuit is integrated with a diplexer on one substrate. The tunable matching circuit has a first and second inductor coupled to the antenna. The second inductor is couple to a first capacitor and a second capacitor. One side of the second capacitor forms an input/output port for connection to a duplexer. One or more of the matching circuit elements is a ferro-electric (FE) tunable component.
