Inspection on Superwide Band 5G Antennas for Communication Applications

The 5th Generation (5G) technology requires a higher data rate, superior bandwidth, improved efficiency, and compact antennas for smartphones to facilitate with different types of super wideband antennas are inspected with design methodology, gain, bandwidth, and other performance parameters are analyzed to find applications in 5G technology. The different types of array antenna provide higher gain but fed with a single port demonstrate similar capabilities as a single antenna. The multiple-input multiple-output (MIMO) antenna having the capability of multipath propagation, higher data rate, enhanced capability, and link reliability, which provides the solution to 5G technology. The substrate integrated waveguide (SIW) antennas explore the advantage of classical metallic waveguides such as low radiation loss, high power, high gain, and high selectivity, and also planar antenna consists of low profile, low cost, lightweight, and ease of integration with microwave circuits. The combined capability of SIW with MIMO structure is the potential candidate for 5G smartphones. The simple SIW antenna simulated using high-frequency structured simulation (HFSS) software tool, which provides the multiple band's resonances from 21 GHz to 50 GHz operating band and reflection coefficient |S₁₁| at 28.66 GHz is -58.577 dB as standard value is less than -10dB.
