Patent ID: 7996035

Claim:
A system comprising: at least one antenna; at least one transceiver communicating with the antenna; a matching network in a communication path between the antenna and transceiver, the matching network comprising: at least a first set of matching elements switchable from a first configuration, in which at least a first matching element in the set is not in the communication path, and a second configuration, in which the first matching element is in the communication path; and a processor controlling the matching network to establish the first and second configurations and to determine first and second respective measures of performance, the processor establishing the configuration having the best measure of performance, wherein first and second sets of matching elements are connected to a common cross line, a first part end of cross line being connected to a switch establishing the first and second configurations, a second part of the cross line being connected to a duplexer or transmit/receive (T/R) switch, the cross line being grounded between the first and second matching elements.
