More Information
Summary:The invention provides an adjustable antenna. The adjustable antenna comprises an antenna, a matching inductor and a phase shifter, wherein the input end of the phase shifter is connected with the antenna and inputs a microwave signal received by the antenna, the output end of the phase shifter outputs the microwave signal after conversion, and the matching inductor is connected between the input end of the phase shifter and ground. By the adjustable antenna, the radiation efficiency of the antenna is improved better, a wide adjustable range can be acquired, continuous adjustment can be achieved, and the adjustable antenna is flexible and convenient. Moreover, if the characteristic impedance of the phase shifter is changed, the adjustment range can be changed, different antennas can be matched, and return loss can be amplified.
