Abstract
Conference Title: 2016 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting Conference Start Date: 2016, June 26 Conference End Date: 2016, July 1 Conference Location: Fajardo, PR, USA A design and analysis of a proximity-fed printed slot antenna with 28/38 GHz dual band characteristics for future 5G wireless applications are presented. To obtain a dual-band at 28/38 GHz that covers 5G applications, an elliptical patch is etched non-concentrically inside a ground plane elliptical slot. The antenna is proximity-fed by a microstrip on the other side of the substrate. Results indicate that the proposed antenna yields a broadband impedance bandwidth greater than 20 GHz (from 20 to more than 40 GHz) defined by S 11 < -10 dB that covers both 5G bands. To reduce the interference between the 5G system and other applications, L-shaped slot is etched off in the feed line to create a notched band of 30-35 GHz. Simulated results show that the designed antenna has dual band at 28 and 38 GHz for 5G system with band notched at 33 GHz. The antenna provides almost omni-directional patterns, relatively flat gain, and high radiation efficiency through the frequency band excluding the rejected band.
