Antenna diversity scheme using a bandpass oversampling and a quick turn of semiconductors

A vehicle or other host station includes first and second antennas, a fast semiconductor switch, a switching controller and an RF receiver. The controller turns on the switch with a calibrated switching rate back and forth to selectively and alternately connect the first antenna to the RF receiver or a load having a calibrated impedance value. In any embodiment using the load, the first antenna may be a parasitic element. The semiconductor switch may be a CMOS device or a gallium arsenide semiconductor switch. A switching control method for use in a vehicle or other host station having the first antenna, the second antenna and the RF receiver comprises, that a switching signal is transmitted from the controller to the switch, and the switch with a calibrated switching rate in response One way to the switching signal and is hergeschaltet to connect the first antenna selectively and alternately to the RF receiver or the load.
