Compact Multiple Wideband Slotted Circular Patch Antenna for Satellite and Millimeter-Wave Communications

It is very important to design the compact and multiple wideband antenna for the several wireless communication system services. Also, ever continuously increasing number of wireless communication population, high data rates and minimum data traffic system is required for the 5G mobile system, beyond 5G (B5G) and next 6G mobile system. Also, satellite communication can be expected to support in the future mobile system with small antenna size. Therefore, in this paper, a compact multiple wide band slotted circular patch antenna is designed and presented for the next-generation wireless and cellular applications whose overall dimension is 13x10x1 mm<^>3. In this paper, a slotted circular with a triangular patch is presented, which will operate in the frequency bands of (16.785-18.057) GHz for satellite communication, mm-wave frequency bands like (26.878-29.128) GHz for 5G mobile service applications, (33.778-46.599) GHz for future 5G applications. The antenna resonates at the 5G mm-Wave frequency band of 28 GHz with the impedance bandwidth of 2.250 GHz. The maximum gain of the proposed antenna is 4.986 dB.
