Abstract
Multi-tap switchable antenna apparatus for use with mobile devices and other applications, and methods of utilizing the same. In one embodiment, the multi-tap switchable antenna apparatus includes a main radiator coupled to an antenna feed or source. Galvanically connected to the main radiator is a plurality of switchable antenna radiators which are in turn connected to an nPmT switch. The output of the nPmT switch can be connected to a variety of differing electronic component impedances. By altering the state of the nPmT switch, the operational length of the antenna (and hence, the operational frequency band of the antenna) can be varied. Performance characteristics associated with a given implementation of the multi-tap switchable apparatus are also disclosed.
