In this communication, a new and small-sized micro-strip antenna is proposed for circular polarization. Four fractal tree structures are embedded at the four corners of the rectangular patch radiator. Trunks of the all fractal trees are placed along the diagonals of the patch to achieve the desired goal. Shapes of the loaded trees are symmetrical along the diagonal. Simulated reflection coefficient bandwidth of 71 MHz (2.275–2.346 GHz) and axial ratio bandwidth of 14 MHz (2.293–2.307 GHz) is achieved in the optimized design. The maximum size of the proposed antenna is 0.215 λ0 × 0.215 λ0 × 0.0122 λ0 at 2.30 GHz. The proposed antenna is small sized and can be a good candidate for portable wireless medical devices, radio frequency identification (RFID) reader, Internet of Things (IoT), and WiMax (IEEE 802.16e, standard) applications.
