Abstract
A 24GHz microstrip phased array antennas with high gain and low side-lobe is designed for antomotive anticollision radar in this paper. The proposed microstrip antenna array is fed by a series-parallel feeding network which can reduce loss of feed network and realize miniaturization of antenna on basis of satisfying requirement of each element of antenna array excited by the unequal amplitude. The simulation results show the 8×12 antenna array has a bandwidth of 1.1GHz. The maximum scanning angle is about ±30°, and the minimum gain about 25dB. In the process of scanning angle, the maximum beam width of E-plane and H-plane is 6°and 14.2°. And the first side-lobe level is −18dB and −19dB.
