Abstract
A dual-frequency reconfigurable micro-strip slot antenna is characterized by comprising a medium substrate, a gap with the length larger than the width is arranged on the medium substrate, the position which is a certain distance away from the left end of the gap is provided with a metal ribbon, one end of the metal ribbon is connected with a floor, the other end of the metal ribbon is connected with an RF-MEMS switch, the other end of the RF-MEMS switch is connected with the floor, and the position which is a certain distance away from the right end of the gap is provided with a micro-strip line. The resonant frequency of the micro-strip slot antenna mainly depends on the length of the gap, the principle that different working frequencies can be obtained by changing the length of the gap is utilized, and therefore the working frequency, the polarization direction and the radiation direction of the antenna are changed in real time by changing the structure and the position of an antenna radiation unit under the condition that the size of the whole antenna is not changed, the integration of the system antenna is achieved, and the size of the system is reduced.
