Dual Band Printed Rectangular Ring-Shaped Monopole Antenna for Wireless Communication

In the present work, printed rectangular ring-shaped antenna with inverted L-shaped strip for dual band wireless communication. Structure of antenna is simple and the size is 34 × 18 mm2. This modified inverted L-shape will give the required bandwidth with good return loss. The simulated results show the dual band from (2.5–3.2 GHz) and (5.09–5.83 GHz) with the center operating frequency at around 2.9 and 5.48 GHz having reflection coefficient less than −10 dB for wireless applications.
