60 GHz Circular Patch-Fed High Gain Transparent Lens Antenna
Keywords:
Dielectric lens, high gain, millimeter-wave antenna, unlicensed 60 GHz bandAbstract
A high gain, low cost and easy to fabricate millimeter-wave (MMW) antenna is presented. To focus the radiation into a very thin main beam, a concept based on employing a cylindrical air cavity with a convex front-end linking a microstrip patch radiator and a transparent dielectric lens is introduced. This principle is applied to enhance the coupling between the patch antenna and dielectric lens at 60 GHz. The design shows very directive and stable radiation patterns in both the E and H-planes. The proposed antenna exhibits a measured gain of 20 dB over the ISMband, as well as high radiation efficiency (greater than 90%). The performance of the proposed antenna makes it a promising solution for various MMW applications, including short distance wireless communications and MMW imaging.
