Design and Simulation of Triple Band Microstrip Patch Antenna for Ku-band, K-band and Ka-band Applications

Abstract

Abstract This paper represents a microstrip patch antenna for future 5G-communication technology. The proposed antenna designs are simulated and their performances are analyzed for different parameters like lower return losses, higher gain, voltage standing wave ratio (VSWR), current distribution, far field radiation and wide bandwidth performance for the tri-frequency band operation in Ku band (12–18 GHz),K-band (18–27 GHz) and Ka-band (27–40 GHz) as per the specified IEEE standard. The proposed antenna has a compact structure designed by CST (Computer Simulation Technology Microwave Studio) software with substrate and patch best suited for miniaturized devices. It consists of PEC (Perfect electric conductor), the determination of the appropriate permittivity and standard thickness of a lossless dielectric superstrate slab layer substrate. The antenna is formed by Copper patch, Copper feed and Copper ground. The dimensions of substrate and patch have been used 40mm×38mm and 20mm×19.5mm respectively. Overall size of antenna is 40mm×38mm×1.6mm. Microstrip line feeding technique has been used. The proposed antenna achieved -52.98 dB gain mobile data applications at 36.802 GHz frequency.
