Dual Band Micro-strip Patch Antennas for 5G sub 6 GHz Smart Mobile Phone and C-Band Application

In this paper, antenna has been design for smart mobile phone application for 5G band 3.4-3.8 GHz and C-Band application. The Via hole and Slotting techniques have been used for designing of antenna. The Self and Mutual inductances of antenna has been optimized. The propose antenna has been designed in four parts. For Mathematical modeling of the proposed antenna transmission line model has been used. The simulation results give Impedance bandwidth in the frequency of S and C Band, 14% impedance bandwidth in S-Band (3.3GHz to 3.8GHz), 5% (4.2 GHz to 4.5GHz) and 4% (4.5-4.7GHz)in C-Band. Design operating notches at three frequencies 3.58 GHz, 4.3 GHz and 4.6 GHz where reflection losses are less than −15dB.
