Microstrip patch antennas (MPAs) are rapidly gaining more attention due tothe proliferation of communication devices and systems with frequenciesbecoming more suitable for the size and performance of this type of antenna.Due to recent advancements in semiconductor technology, high dielectricconstant materials are used to achieve additional size reduction which has madeMPAs very useful and popular in the design of mobile devices and wirelesssystems. However, MPAs suffer from problems associated with narrow bandwidthand low gain. Techniques employed for improving the performance of MPA hinge ontweaking features such as the patch size, substrate height, ground plane sizeand feeding method. In view of this, this research designs and analyzes theperformance of an X-band MPA for wireless systems using CST Microwave Studio.Including the ground plane, the proposed design has a low profile structure of17 mm x 17 mm x 1.6 mm which is suitable for wireless systems. The proposeddesign also resonates at a frequency of 10 GHz with an omnidirectionalradiation pattern exhibiting a gain of 7.2 dBi. Return Loss, VSWR, Gain andRadiation Pattern are the performance indicators employed in this research. Theproposed MPA design demonstrates marked performance improvement whenbenchmarked with a similar MPA designed for 5G applications.
