A High Gain Planar Monopole Hexagonal Circular Slotted Patch Antenna For Ultra-Wideband And Multiple Frequency Range Applications

This paper introduces the designing of a high gain planar monopole hexagonal circular slotted patch antenna for ultra-wideband and multiple frequency range applications. The substrate of the antenna is constructed using FR4 epoxy substratum. The size of the antenna is 42mm×36mm×1.6mm. The top patch and the bottom plane of the antenna are designed by copper material. The attains the −10dB bandwidth from 1.5 GHz to 15 GHz. The overall bandwidth of the proposed antenna is 13.5 GHz. The resulted resonating frequency of the antenna is 14.3 GHz. The reflection coefficient of the antenna at its resonating frequency is −30 dB. The attained overall gain of the antenna has come out to be 6.79 dBi. The peak gain of the antenna is the same as the net gain of the antenna at its resonating frequency. The peak gain frequency of the antenna is the same as the resonating frequency which is 14.3 GHz. The antenna efficiency has come 81.87%. The top current dispensation of the antenna at hexagonal circular slots edges goes as high as 91.97 A/m at its resonating frequency. The proposed antenna is best suitable for GPS, WiMax, WBAN, WiFi, and ultra-wideband frequency range applications.
