ULTRA WIDEBAND SMALL SIZE Y-SHAPED MICRO STRIP PATCH ANTENNA DESIGN

Abstract

With the developing technology in recent years, wireless mobile devices that can performmultiple tasks at the same time are desired by users. But wireless devices; The problem of powerconsumption, dimensions, frequency spectrum constraint, and desire for high performance haveencouraged researchers to develop new technologies. Ultra-Wideband communicationtechnology can be considered as a short-range wireless mobile communication system with lowpower consumption and high data rate. Due to the broadband requirements in the field ofcommunication, broadband antennas have become popular today. Ultra-Wideband increasesthe need for broadband antennas with reduced dimensions in both military and commercialapplications. In this context, microstrip antennas come to the fore with their many remarkablefeatures such as their simple structure, small dimensions, applicability to smooth and inclinedsurfaces, and being durable when applied to hard surfaces.Within the scope of this study, a microstrip patch antenna with a Y-shaped structure operatingbetween 3.78 GHz and 13.56 GHz was designed for ultra-broadband applications. CSTMicrowave Studio program was used in designs. The antenna is designed on the RT Droid 5880base material with 1.57 mm thickness, 2.2 epsilon value, and 0.0009 tangent loss. An annealedcopper conductor with a thickness of 0.02 mm is used for the antenna part and the ground plane.The antenna has a very small and compact structure with dimensions of 20 mm × 21 mm × 1.57mm. In the simulations, the bandwidth, S11, and radiation pattern were examined and it wasevaluated that it could be used in wireless body area network applications due to the small sizeof the antenna.&nbsp; </p
