In this paper, narrowband tuning is achieved using PIN diodes. The circular patch antenna is fed by Coplanar Waveguide (CPW) feed. The circular patch is embedded inside a rectangular patch shaped slot. Two square slots of equal size are found on either side of the patch. The square slots can be either connected or disconnected to the rectangular slot by switching OFF or ON a pair of PIN diodes. The antenna can tune frequency in the range of 0.1 GHz between the WLAN frequencies 4.8 GHz, 4.9 GHz and 5 GHz. © 2018, Institute of Advanced Scientific Research, Inc. All rights reserved.
