ABSTRACT

A 24×24 microstrip array antenna for Doppler radar is presented. For the low side lobe, the feeding network of microstrip array antenna is used for Taylor series amplitude weighting. The side lobe of microstrip array antenna is less than -18.5 dB at 24.15GHz. The proposal design is confirmed by both simulation and measured results.
