Metamaterial-based inset-fed patch antenna with enhanced gain for sub-6 GHz 5G band
This paper presents a metamaterial-inspired patch antenna is designed for fifth-generation (5G) communication systems. The proposed antenna, with a compact dimension of 65 × 65 mm2, employs an inset-fed patch on an FR4 substrate with a defected ground plane to enhance impedance matching. A 5×5 array of metamaterial uni...
