Abstract:
1. An antenna switching arrangement, comprising: an input port coupled via a fourth transmission line to a fourth junction of a quadrature arrangement of quadrature transmission lines also provided with a first, a second and a third junction; the first junction provided with a first switch operable to selectively couple the first junction to ground; the second junction provided with a second switch operable to selectively couple the second junction to ground; the third junction provided with a third switch operable to selectively couple the third junction to ground; the first junction coupled via a first transmission line to a first output port; the second junction coupled via a second transmission line to a second output port; a terminating junction coupled via a third transmission line to the third junction; a fourth switch operable to selectively couple the terminating junction to ground; and a resistor coupled between the terminating junction and ground; at least one of the first, second, third and fourth switches are inductors.
