Abstract

Circuits and methods of operating multiple antennas using a shared controller are provided. In one embodiment, a method includes coupling, in a first configuration, a first antenna to the shared controller and decoupling a second antenna from the shared controller. The first antenna is coupled to the shared controller using a first matching circuit and a first filter. The method further includes operating a controllable activation component to define a second configuration state formed by decoupling the first antenna from the shared controller and coupling the second antenna to the shared controller. In this embodiment, the second antenna is coupled to the shared controller using a second matching circuit and a second filter. At least one capacitor of the first matching circuit is used in the second filter and at least one capacitor of the second matching circuit is used in the first filter.
