Abstract
A frequency reconfigurable antenna is designed and presented for 5G applications. The proposed antenna is designed by using two T shaped patches positioned inversely to each other and connected by a PIN diode. Here the bottom T shaped patch is inverted and connected to the micro strip line feeding. FR4 substrate is used as dielectric and the backside ground is maintained partial with a rectangular open slot is etched opposite to the feed point. The PIN diode acts as a switch to change the operating frequency of the proposed antenna in-between n77 and n78 bands of 5G applications. The simulated analysis of proposed 5G antenna showed that, when diode is in OFF conditions it operates at 3.5 GHz with operational band covers from 3.34 GHz to 3.7 GHz. Similarly, when diode is in ON condition the antenna operated at 3.7 GHz with operational band covering from 3.47 GHz to 3.94 GHz. The performance of the frequency reconfigurable 5G antenna for OFF and ON conditions is compared with the help of S11vs frequency, VSWR and radiation pattern curves and presented. The proposed antenna maintained similar radiation coverage at respective resonant frequencies for OFF and ON conditions making it suitable for future 5G applications.
