Abstract
Series fed microstrip patch antenna arrays are widely used for millimeter-wave radar applications due to their simple structure, high gain, and low cost. However, they usually suffer from narrow impedance bandwidth. In this paper, a 79GHz series fed microstrip patch antenna array with bandwidth enhancement and sidelobe suppression is presented. The obtained simulation results showed a maximum sidelobe level of -19dB and -17dB at E-Plane and H-Plane, respectively, as well as a -10dB impedance bandwidth of 4.14GHz and a high gain of 22dBi.
