ANTENNA TRACKER ARCHITECTURE FOR AN ELECTRICAL BALANCED DUPLEXER

A communication device includes an antenna tracker having a circuit architecture that includes at least one L-C resonance circuit component with an adjustable resonance frequency value. In particular, each of the L-C resonance circuit components may include a tunable capacitor and an inductor coupled in parallel. The antenna tracker may be single-ended and include at least one ground coupling, while in some embodiments, the antenna tracker may be differential. The circuit architecture of the antenna tracker may enable the antenna tracker to increase an impedance coverage range of the communication device, thus increasing a range of impedance within which an antenna impedance may be effectively tracked and matched, enabling effective isolation between the transmitter and receiver across an increased range of antenna impedance.
