Abstract
An investigation of an ultra-wideband rectangular monopole with circular ring antenna for wireless communication systems is reported. The antenna is designed, simulated, invented, and tested experimentally. It operates over frequency range of 2.56-13 GHz with a return loss of 10 dB. The dimensions of designed antenna is 40 mm × 40 mm with an electrical size of 0.34λ× 0.34λ at 2.56 GHz frequency. It is fed by a 50-Ohm coplanar waveguide and printed on a single side FR-4 substrate with a relative permittivity of 4.3 and a thickness of 1.6 mm. This designed antenna exhibits bidirectional radiation patterns over the entire impedance bandwidth with more than 2.8 dB peak gain for the entire frequency range. The simulation results are reasonably in good agreement with the experimental results.
