Abstract
A simple design for solar powered frequency sensors is presented. The design is based on a rectenna composed of a frequency reconfigurable microstrip antenna, a rectifying circuit, and a low pass filter. The operating frequency of the antenna can be tuned in the range between 2 and 2.8 GHz, and, in this frequency range, the rectifier can effectively perform the conversion from RF to DC. By the measured results of the rectenna, the average conversion efficiency within the operating bandwidth of 33% is 73% over a resistive load of 1 kΩ at a power density of about 0.8 mW/cm2. A frequency sensor is successfully implemented by integrating the frequency reconfigurable rectenna with a preprogrammed microprocessor powered by solar cells.
