RECONFIGURABLE COMPOSITE RIGHT/LEFT-HANDED TRANSMISSION LINE ANTENNA BASED MINKOWSKI- STEPPED IMPEDANCE RESONATOR STRUCTURE FOR 5G COMMUNICATION NETWORKS

This paper presents a design of a metamaterial antenna based on a Composite Right/Left-Handed Transmission Line (CRLH-TL). The proposed antenna is constructed from 17 unit cells of CRLH-TL with an Electromagnetic Band Gap (EBG) of the 1st order Minkowski-Stepped Impedance Resonator (SIR). The antenna is printed on a Taconic RF-43 substrate with thickness=1.57 mm , with an overall size of 204.6 * 40 mm2. The CRLH and fractal structure achieve frequency reconfigurable, compactness, multiple-bands , high radiation performance. 17 PIN diodes are used to control the antenna performance and show its frequency reconfiguration; 6 cases are selected among 217 cases due to space limitations. As a result, the antenna design can operate in various wireless bands such as Radars [4.2-4.3 GHz and 4.6-4.9 GHz], Wi-Max [5.8 GHz], Wi-Fi [4.9 GHz, 5-5.8 GHz], and 5G sub-6-GHz [4.6 GHz and 5-5.9 GHz], which indicates the novelty of the proposed antenna and the possibility of using it in various applications. Computer Simulation Technology-Microwave Studio (CST-MWS) is used to design and simulate the proposed antenna. The Minkowski -SIR antenna achieved dual-band operation with maximum gain equal to 12.4 dBi and 10.8 dBi at 4.89 GHz and 5.4 GHz, respectively.
