Abstract
This letter presents a compact 77 GHz millimeter-wave comb antenna, exhibiting suppressed side-lobe and enhanced gain. In the conventional tapered comb antenna, a lager-width of the radiating stub performs a decreased resonance ability. By loading coupling patches and cutting notches on the elements, it is possible to increase the resonant ability and design an antenna array with a satisfying radiation pattern and gain. Low cost, low profile and ease of fabrication are further advantages of the proposed antenna array. Two arrays (1 × 13 and 4 × 13) operating at 77 GHz are designed to verify feasibility. The measured gain of the 4 × 13 antenna at the resonant frequency is 19.11 dBi, while the side-lobe is below −17.37 dB, in accordance with the simulation results, which indicate that the 77 GHz comb antenna is an option for radar communication systems requiring high gain and side-lobe suppression.
