Design and fabrication of different shapes of Microstrip Patch Antenna

This work is proposed to design and fabricate microstrip patch antennas MPAs operatiThis work is proposed to design and fabricate microstrip patch antennas MPAs operating at (28) GHz that provides adequate radiation performance reliable for (5G) application which proceeds through the following steps.In the first senario, the rectangular, circular and triangular MPAs are designed to operate at (28) GHz by implementing Computer Simulation Technology (CST) software. The MPAs are built on the dielectric substrate material named Rogers (RT5880) of relative permittivity(Ԑ_r=2.2). The simulation results reveal that a smaller antenna patch area of the order of (7.86) mm2 is achieved with TMPA, while the best reliable value of (S11) and voltage standing wave ratio (VSWR) is obtained with CMPA. while, the computed results of the fundamental antenna parameters such as gain, directivity, bandwidth and efficiency are found to be obtained with RMSA, which are (6.63) dB, (7.09) dB, (0.967) GHz and (90%), respectively.
