Multi-band hand of god antenna with functionality variation with use of slots and feed position

Abstract

This article investigates different versions of a new multi-band micro-strip antenna design. NASA inspired the antenna design from “Hand of God” galaxy discovery. A multi-band operation between 0.15 and 8 [GHz] is obtained and captures up to 10 frequency bands. The antenna has a small area of 4 x 5 cm2 and is printed on 1.6 mm epoxy-FR4 substrate. Adding slots and changing the feed position, led to different designs and increase in multiband operation. Moreover, varactors are mounted on antenna surface, which resulted in frequencies as low as 50 MHz and as high as 8 GHz when. S11 simulations results were successfully compared with measured ones. Applications include different mobile generations, TV and different IoT systems. © 2019 ASTES Publishers. All rights reserved.
