Abstract
In this paper, a two-port dual-band antenna is designed with high isolation. The beak-shaped radiator and open stubs are used to achieve miniaturization of the antenna. A T-shaped stub is used to isolate the antenna at higher frequencies whereas open-ended slots effectively miniaturized the antenna size thereby increasing the impedance and isolation by more than 20 dB. The isolation is enhanced due to the suppression of current between radiators without increasing the size of the MIMO antenna for lower frequencies. The proposed antenna parameter CCL, DG, TARC and ECC reflects better diversity performance. The two-port antenna covers 2570, 2300, 2496, 3400, 3600 MHz (LTE 38, 40, 41, 42, 43) 2500, 3500, 3700 MHz (5G n7, n48, n77) 5.15/5.85 GHz (WLAN), 2.4/5.0 GHz (Wi-Fi) and 2.45/5.8 GHz (ISM) sub-6 GHz bands and can be a good choice for wireless communication.
