Abstract
Microstrip patch antennas (MPAs) are rapidly gaining
more attention due to the proliferation of communication devices
and systems with frequencies becoming more suitable for the size
and performance of this type of antenna. Due to recent
advancements in semiconductor technology, high dielectric
constant materials are used to achieve additional size reduction
which has made MPAs very useful and popular in the design of
mobile devices and wireless systems. However, MPAs suffer from
problems associated with narrow bandwidth and low gain.
Techniques employed for improving the performance of MPA
hinge on tweaking features such as the patch size, substrate
height, ground plane size and feeding method. In view of this, this
research designs and analyses the performance of an X-band
MPA for wireless systems using CST Microwave Studio. Including
the ground plane, the proposed design has a low-profile structure
of 17 mm × 17 mm × 1.6 mm which is suitable for wireless
systems. The proposed design also resonates at a frequency of 10
GHz with an omnidirectional radiation pattern exhibiting a gain
of 7.2 dBi. Return Loss, VSWR, Gain and Radiation Pattern are
the performance indicators employed in this research. The
proposed MPA design demonstrates marked performance
improvement when benchmarked with a similar MPA designed for
5G applications.
