ABSTRACT
The fifth-generation mobile communication system (5G) is penetrating into all industries and fields of the economy and society, which needs miniaturized, wide-band, tunable antennas. In this research, a 26GHz rectangular microstrip patch antenna is designed and simulated, with a mini size of 8.3mm × 10mm × 0.254mm. And the parameters of the patch are 5.7mm × 3.8mm × 0.035mm. This antenna resonates at 26GHz with a bandwidth of 720MHz, a gain of 4.662 dBi and an efficiency of 89%. The inset feed transmission line is adopted to match the patch and 50 microstrip feedline, with an insert depth of 0.9mm. As for the material, a Roger 5,880 substrate was selected, whose dielectric constant is 2.2. The parameters of the antenna were calculated and the simulated results have been displayed and analyzed using the Computer Simulation Technology Microwave Studio.
