Abstract:
Fifth-generation (5G) wireless communication systems employ millimeter-wave (mm wave) frequency bands to achieve a very broad spectrum for high data rate transmis sion. To meet the requirements of the system, the design of antenna arrays with high
capacitance and exibility are essential. Thus, in this thesis, the design and perfor mance analysis of single element, 2x1, 4x1, 2x2, 4x4, and 8x8 metamaterial inspired
millimeter wave antenna (MIA) arrays are proposed. Rogers' 5880, a substrate mate rial with a 2.2 dielectric constant and a thickness of 0.35 mm, is used in the design of
the antenna elements to operate at a 38 GHz central frequency. The simulated design
of the single, 2x1, 4x1, 2x2, 4x4, and 8x8 MIA arrays bandwidth and total e ciencies
(η%) are: 1.971 GHz, 2.278 GHz, 4.704 GHz, 2.51 GHz, 4.156 GHz, 5.44 GHz; and
95.55 %, 94.01 %, 95.87%, 95.58%, 93.21%, and 85.38% respectively. As compared
to other works, improved performance has been achieved by considering the e ect of
metamaterials on the radiator and at the ground of microstrip patch antennas (MPA).
The selected type of metamaterials alters the current distribution of the radiating patch
that enhances the fringing elds at the edge of MPAs, which inspires the radiation of
antennas and reduces the surface wave loss at the radiators' ground plane. The pro posed MIA antenna arrays have improved on the drawbacks of traditional MPAs in
terms of bandwidth, VSWR, and return losses to enhance the data rate and device to
device communication for 5G wireless systems
