摘要: A dielectric lens antenna feeding with microstrip patch antennas for long range radar application is presented. Using the microstrip patch antenna to feed the lens antenna is easy to implement due to its simple and compact size. Besides, the lens antenna can be easily achieved high gain and low side lobes. To achieve broader field of view for the radar application, two feeding microstrip patch antennas are utilized, and each of which has 10 degree of half-power beamwidth covering field of view of 20 degree. The measurement peak gain, half-power beamwidth, and side-lobe level are 20.2 dBi, 9 degree, and -16 dB, respectively. The measurement results show the input impedance of the proposed lens antenna is well matched to 50 Omega. All the measurement and simulated results are in good agreement.
