“…Table 2 shows the characteristics comparison between the anticipated antenna and the research results published in the recent years [5][6][7][8][9] in terms of electrical size, impedance bandwidth (4G/5G bands), isolation, gain, and feed configuration is tabulated. The features of the proposed antenna are low profile, larger bandwidth, high isolation and very high gain, low XPD, stable radiation pattern.…”

“…A compact dual polarized antenna for 2G/3G/LTE base station (BS) applications is achieved by incorporating the magnetic dipole antenna with differential feeding mechanism and printed dipole antenna with γ‐type feeding network 5 . In Reference [6], a wideband dual polarized flared bow tie dipole antenna with shorting post is proposed to attract low‐profile geometry for 5G base station applications. The design incorporates a pair of orthogonal printed flared bow tie dipole with shorting post and fed with a coaxial probes used to obtain wideband and stable radiation pattern.…”

Nature inspired high gain ±45dual polarized Ixora coccinea petal shaped massive multiple input multiple output antenna element is designed and developed with special feeding mechanism operating for 3rd Generation Partnership Project long term evaluation-time division duplexing mode for (2496-2690 MHz) and Sub-6 GHz of 5G Band 42 (3.4-3.6 GHz)/Band 43 (3.6-3.8 GHz) for macro cell communications are explored. Dual slant polarization is achieved by orienting two such petal shaped dipole antennas in ±45 .To validate the proposed antenna, the prototype is manufactured and measured. The antenna provides the bandwidth of 41.26% (2.5 to 3.8 GHz) with S 11 < À15 dB, and port-to-port isolation>40 dB. Simultaneous operation of 4G and 5G with unidirectional stable radiation is achieved with broad-beam width of 73 ± 1.5 in the ±45 planes and gain varies from 10 to 11 dBi over the operating band. Due to its full planar structure the proposed antenna is easy to be fabricated.
