Defected Circular Slot Dual Band Antenna for S, C and X-Band Applications

In this communication, a dual band antenna with defected circular slot in T shape geometry on top and defected ground structure on bottom is presented. The proposed design operates with two frequency bands (3.18–3.87 GHz)/(4.66–10.05 GHz) at resonating frequencies 3.68 and 6.78 GHz which validates the applications of S, C and X-bands.
