Abstract
A Dual polarized antenna with guard band characteristics with modified dual-polarized dipole antenna using the grounded coplanar waveguide (GCPW) filter for the 3G, 4G, and 5G base station applications are explored in this research paper. Firstly, the modified dipole arms are arranged in a crisscross manner to generate orthogonal polarizations with CPW feed designed to operate in the frequency band of 1.6-3.6 GHz. Secondly, meandered slot GCPW is patterned on the modified dipole antenna and is modeled to provide band stop characteristics with sharp roll-off for 3G, 4G, and 5G. As an outcome, the anticipated antenna is operating in the band of 1.6-2.78 GHz and 3.2-3.8 GHz for VSWR < 1.6 with a guard band of 2.85-3.18 GHz. The proposed antenna provides the isolation of more than 30 dB, the half-power beam width of 70o±1 0, and realized gain of 8.73 dBi throughout the operating band of 3G, 4G, and 5G for Base Transceiver Station (BTS) applications. Simulation studies shows that for the deployed cell sites, the maximum downlink data rate and throughput were 2.03 Mbps and 50.97 Mbps, and the maximum uplink data rate and throughput were 0.15 Mbps and 35 Mbps. The maximum received power and SNIR are -50 dBm and 60 dB, and the maximum RSRP of -65 dBm, RSRQ of -11 dB, and RSSI of -40 dBm.
