Abstract: A planar, slot-based, simple and circularly polarized (CP) antenna is presented in this work. It consists of a square shaped slot that is fed via a coplanar waveguide (CPW) 50-ohm feed. The CP slot operates at a center frequency of 2.5GHz. Here, the corners are modified by adding small symmetric rectangular slot extensions to produce CP based waves. The plots obtained on simulation and measurement of the fabricated prototype display commendable similarity between each other. Very wide axial ratio bandwidth (ARBW) of 35% along with a maximum gain of 3.5dBi at 2.5GHz were accomplished. � 2019 European Association on Antennas and Propagation.
