Abstract :
A novel compact switched slot antenna has been proposed in this paper, it consists of two slots cut in metal plane and a single feeding stub, and the slots are controlled by two switches mounted in the center of them. When each switch is open, the related slot could be excited, while the short one would be idle and serve as a reflector, the two elements could lead to unidirectional radiation pattern. By switching the switches, the pattern of antenna could be switched accordingly. Experimental results show this antenna has good performance, and the front to back ratio is better than 12 dB.
