1. A dynamic antenna tuning system comprising:
an antenna controller, the antenna controller generating a first signal and a second signal; and
a tunable antenna, the tunable antenna comprising a plurality of switches, the plurality of switches comprising a first switch and a second switch, the first switch being controlled by the first signal, the second switch being controlled by the second signal, the switches being controlled by the antenna controller to dynamically configure the antenna in one of a plurality of antenna geometry configurations, each of the plurality of antenna geometry configures having an associated antenna structure, each associated antenna structure providing a different radiation pattern, a first of the plurality of antenna geometry configurations being provided when the first signal is active and the second signal is inactive, another of the plurality of antenna geometry configurations being provided when the first signal is inactive and the second signal is active; and wherein the first switch is mounted on a first antenna structure of the plurality of antenna geometry configurations; and
the second switch is mounted on a second antenna structure of the plurality of antenna geometry configurations; and wherein
the plurality of antenna geometry configurations comprise a Planar inverted F Antenna (PIFA) type antenna configuration.
