This letter reports a miniaturized, multiband patch antenna capable of detecting thee frequencies in conjunction with CMOS array detector element for real‐time multi‐frequency imaging in terahertz (THz)‐band.Multi‐frequency operation is desirable for THz CMOS camera design, which is achieved by using stubs and slot‐type split ring resonator on the patch antenna connected to the on‐chip CMOS detector. The proposed antenna is designed at three‐bands of 218, 338, and 400 GHz corresponding to the atmospheric transmission windows. And the performance of the multiband THz antenna is successfully demonstrated using the finite‐difference time‐domain method. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett, 2012
