NEW COMPACT DESIGN OF RECTANGULAR SLOTTED HEXAGONAL MICROSTRIP PATCH ANTENNA

ABSTRACT In this paper a HEXAGON shaped Microstrip Patch Antenna has been designed, simulated and analyzed in Zealand IE3D upbringing. The antenna is fabricated with a dielectric constant of 3.4 and loss tangent of 0.002. Microstrip patch antenna becomes very popular day by day because of its ease of analysis and fabrication, inexpensive, trivial, easy to feed and their striking radiation characteristics. Although patch antenna has several advantages, it has also some drawbacks such as restricted bandwidth, and a potential decrease in radiation pattern. Different techniques for bandwidth improvement of usual rectangular microstrip antenna are anticipated in this paper. By increasing the height of patch , escalating the substrate thickness and decreasing the permittivity of substrate the %bandwidth is increased. IE3D Software is used for the simulation and design calculation of microstrip patch antenna. The return loss, VSWR curve, directivity and gain are evaluated. The designed antenna operates in the frequency range of 1.45 to 2.62 GHz having the optimum bandwidth of about 57.63%. Using IE3D software put together of Zeland, according to the set size, the antenna is simulated.
