Abstract
A communication device includes: a first antenna operable to receive wireless communication signals; a second antenna having plural leads, the second antenna operable to output wireless communication signals; a connection including plural conductive lines having respective first ends and second ends, the connection coupled with the leads of the second antenna at the first ends of the lines; and a switch coupled with the second ends of the connection, the switch operable to provide one of selective shorting and isolation of the leads. One method of communicating includes: forming a first antenna; forming a second antenna; receiving wireless interrogation signals using the first antenna; outputting wireless identification signals using the second antenna; opening a coupling intermediate plural leads of the second antenna during the receiving; selectively shorting the leads of the second antenna during the outputting; and providing a low load impedance of the second antenna during the receiving.
