摘要：

This paper proposes a new design of a 2x2 microstrip array antenna with spiral stub for a 5G communication system at the resonant frequency of 3.5 GHz. Spiral stub is useful for increasing the bandwidth value of the proposed antenna. The spiral stub is designed using a microstrip line with an impedance of 70.7 ohms. This study proposes three antenna models by adjusting the number and dimensions of the spiral stubs. From the simulation results using EM Simulation, the optimal bandwidth is obtained when the number of spiral stubs (n) = 3 with dimensions of spiral stub W-stub = 18.5 mm and L-s = 8 mm . The bandwidth of the proposed antenna is 0.8 GHz or an increase until 88.88% compared with array 2x2 without spiral stubs. Furthermore, the gain of the proposed antenna is 10.67 dB at the resonant frequency of 3.5 GHz. This research is very useful for bandwidth for the of 5G communication
