Abstract

ABSTRACTThis article proposed a novel compact antenna design for K‐band applications using electromagnetic band gap (EBG) structure. A very compact design has been fabricated on a Rogers Duroid 4350 substrate and is multilayered with another substrate of similar dimensions. The design consists of circular patch and circular rings both as active antenna elements and EBG structures. The proposed antenna resonates at a frequency of 18.72 GHz with a wide band of about 1 GHz and a gain of 8.1 dBi along with a reduced side lobe level of −11.6 dB. The electromagnetic band structure incorporated along with a multilayer structure resulted in enhancement of impedance bandwidth and improvement in radiation characteristics. © 2015 Wiley Periodicals, Inc.
