16 ELEMENT RECTANGULAR PATCH ANTENNA ARRAY

Abstract: A microstrip patch antenna consists of radiating patch on one side of dielectric substrate and has the ground plane on other side. The study of microstrip patch antennas has made great progress in recent years. Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity. Moreover, the microstrip patch antennas can provide dual and circular polarizations, dual-frequency operation, frequency agility, broad band- width, feedline flexibility, beam scanning omnidirectional patterning. This work explores the performance enhancement of microstrip patch antenna. The antennas are analysed using the different antenna parameters like Radiation pattern, Gain, Return loss, Directivity and Radiation pattern. Mobile communication systems of today needs antennas with high gain, big bandwidth, and small size that can provide greater performance over a wide frequency spectrum. The design of a 16-element microstrip patch antenna array is proposed in this study, which employs the corporate series feed technique excited by one port via a T-Junction power divider. For maximal radiation, substrates with a low dielectric constant are desirable. The array's bandwidth ranges from 26.42 to 28.94GHz, with a gain of 17.1dB. CST Microwave Studio Suite is used in the simulations.
