ECO-CONSCIOUS DESIGN OF SLOTTED MICROSTRIP PATCH ANTENNAS FOR MULTI-BAND 5G COMMUNICATIONS

The fifth-generation (5G) of communication era requires multi-band antennas that are
very small, high-gain, and compact to satisfy the rising criteria of high data rates, reliability, and
energy efficiency. The use of microstrip patch antennas (MPAs) has been very popular because it is
low profile, easy to make and economical. However, traditional substrates and fabrication methods
have environmental issues as in most cases non-biodegradable materials are used and a lot of energy
is consumed in the production process. To overcome those difficulties, the present research suggests
an environmental-friendly design and simulation of slotted patch antennas of microstrip in the multiband 5G use. The antenna has strategically designed slots on the radiating patch to resonate at various frequencies bands including sub-6 GHz and millimeter-wave frequencies used in 5G standards.
Dielectric materials that are environmentally sustainable (e.g. biodegradable composite materials),
and recyclable substrates are considered and compared with traditional ones to point out on the
trade-offs between performance and environmental footprint. The proposed antenna is simulated by
full-wave electromagnetism simulation and exhibits better impedance bandwidth, gain and radiation
efficiency over desired frequency bands without sacrificing mechanical flexibility and environmental
friendliness. The findings show that sustainable materials have the ability to perform relatively well
with traditional materials and with a substantial decrement in the ecological impact of the antenna
manufacturing process. This effort creates a gateway to green 5G antenna systems, which will lead
to green and energy-efficient wireless communication systems in the next generation of devices.
