A Novel Monopulse Microstrip Antenna Array with Compound Feed Network
In this paper, a novel feed network design is presented, with which every microstrip line array of antenna is fed at the edge side with the middle of the row shorted and in E-plane the adjacent subarrays are fed with 180 degrees phase difference. This proposed feed network can suppress the near coupling problem in traditional monopulse microstrip antenna array design. Furthermore in order to minish the loss of substrate and microstrip feed line, a waveguide one-plane feed network and waveguide comparator are used, which is connected with every line array by SMA-waveguide connector. The simulated results have demonstrated that the-19 dB side-lobe level for the sum pattern and 32 dB null depth for the difference pattern have achieved.
