Investigation of W-band Integrated Horn Array by Using Full-wave Simulation

To obtain a very good performance antenna in W-band, an integrated horn array with matching network of the antenna/mixer is investigated. The array is mounted on the wafer substrate, where a quasi-optically fed mixer is integrated with some annular slots. High gain and wide-band have been realized, and a minimized size has been obtained due to this compact structure. Meanwhile, to design this device efficiently, a modified alternating-direction implicit pseudo-spectral time-domain method combining with a hybrid matrix manipulation technique is developed. Full-wave simulation is verified at the design distributed stage. Numerical results are in very good agreement with the experimental data.
