'HQVH 'LHOHFWULF 3DWFK $UUay Antenna- A New Kind of Low-Profile Antenna Element For 5G Cellular Networks B.Praveen Balaji, R.Sriram UG Scholar, Jaya Engineering College, Chennai. praveenbalaji8@gmail.com,sriram3838@gmail.com
ABSTRACT By replacing the metallic patch of a microstrip antenna with a high permittivity thin dielectric slab, a new type of patch antenna, designated as the dense dielectric patch antenna(DD patch antenna),is proposed. At lower microwave frequencies, it has similar performance as the conventional metallic circular microstrip antenna operated in the fundamental TM11 mode. This array antenna is proposed and designed with a standard printed circuit board(PCB) process to be suitable for integration with radio-frequency/microwave circuitary. The proposed structure employs four circular shaped DD patch radiator antenna elements fed by a 1-to-4 Wilkinson power divider surrounded by an electromagnetic bandgap (EBG)structure. The DD patch shows better radiation and total effeciencies compared with the metallic patch radiator. For further gain improvement, a dielectric layer of a superstrate is applied above the array antenna. The calculated impedance bandwidth of proposed array antenna ranges from 27.1 GHz to 29.5 GHz for reflection coeffecient (S11) less than -10dB. The proposed design exhibits good stable radiation patterns over the whole frequency band of interest with a total realized gain more than 16 dBi. Due to the remarkable performance of the proposed array, it can be considered as the best candidate for 5G communication applications.bandgap(EBG)

A Patch Antenna is a type of radio antenna with a low profile, which can be mounted on a flat surface. It consists of a flat rectangular sheet or "patch" of metal, mounted over a large sheet of metal called ground plane. The assembly is usually contained inside a plastic radome, which protects the antenna ,Q WKLV SDSHU D QHZ GHQVH GLHOHFWULF '' SDWFK DUUD\ structure from damage.
