Abstract
AbstractThe use of miniaturized antennas in wireless communications is very common. In the current paper, a miniature coplanar-waveguide fed-rectangular patch antenna with semicircular ground is presented. The antenna performance was studied at two different configurations; straight and bent. Cross lines were added to ensure the obtained frequency band. Different parameters were evaluated including return-loss, radiation-pattern, gain and band-width. These parameters were analyzed numerically after twisting along both X and Y axis. Additionally, a prototype of the straight structured antenna is fabricated, and compared with the simulation results. The numerical results show high return loss (− 33 dB) at the straight structure, while the measured return loss decreased to − 28 dB. The bandwidth was 0.75-GHz in case of the straight structure and the measured bandwidth 0.18 GHz. The obtained gain at the resonance frequency is − 13 dB. Moreover, the proposed antenna resonates at frequency 3.22-GHz making it suitable for wireless communications, WIMAX and microwave S-band applications.
