Abstract
The present invention provides a control apparatus of an antenna array. The control apparatus of an antenna array comprises a control circuit including a serial interface circuit connected to the first switch and the second switch by a first control line and a second control line separately, and an antenna coupled between the first switch and the second switch. The serial interface circuit controls On/Off status of the first switch and the second switch separately through the first control line and the second control line. Furthermore, the control circuit and the others can be connected serially through the included serial interface circuits to increase the number of antennas.
