Abstract
This paper presents a frequency reconfigurable DRA. The size of the antenna is approximately 50 mm by 40 mm, thus it can be considered a compact design. This antenna was designed using Rogers RO4003 substrate and the DRA material used was Eccostock HIK. To achieve frequency reconfiguration, the length of the antenna feedline was reconfigured by the means of RF switches. The proposed design consists of four configurations and all those conditions achieved reflection coefficient of less than −10 dB. The antenna also produced consistent gain for all configurations with average gain of 5 dBi. The switched frequencies from the proposed antenna can cover 5G New Radio Bands n48, n77 and n78.
