A lightweight rectangular microstrip patch antenna with high gain and low cross-polarization characteristics for 5G wireless applications is designed using a slotted feed line by proximity coupled feeding and defected ground structure techniques. The proposed model operates in the sub-6GHz (f=3.5GHz) band, with a narrow band of 3.5GHz (210 MHz). The design's dimensions are (43.36×35×1.575) mm3. The radiation efficiency of the antenna is improved by using defected ground structure and slotted strip to increase bandwidth, gain, efficiency, and reduce return loss. The simulation results show a 6.62 dB realized gain and high performance of 89%. Reflection coefficient (S11) and voltage standing wave ratio in this antenna configuration are -21.8 dB and 1.17 dB, respectively, with a -52.4 dB of low cross-polarization. |
