Abstract
Wireless communication systems are operated in each different frequency band. Also, it will be much comfortable and convenient for the single device of small size to be able to cover the multiple functions. Therefore, in this paper, a compact multi-band slotted circular patch antenna is designed and presented for the next generation wireless and cellular applications whose overall dimension is 15x12x1.6 [mm]. In this paper, triple band circular antenna with triangular slot patch is presented, which can operate in the Ku-band, Ka-band and mm-wave frequency bands of 5G mobile service applications. The antenna is designed to operate in the frequency ranges 16.593-18.08[GHz], 23.42-25.64[GHz] for satellite communication, radar application and 27.7-29 [GHz] for 5G mm-wave services. The first band presents in the Ku-band and the second presents in the Ka-band respectively. The maximum gain of the proposed antenna is 8.478 dB and the maximum efficiency is 89.34%.
