Design of a High-Gain, Slotted Ultra-Wideband Antenna with T-shaped slots for Millimeter-Wave Applications

Abstract

Millimeter wave (mmWave) is a crucial frequency range for fifth-generation (5G) mobile communication, characterized by wide bandwidth and higher data rates. Antenna components will be small, wideband, and high-gain for use in 5G systems. This study presents the design and simulation of an ultra-wideband rectangular antenna with T-shaped slots, developed using an evolutionary-oriented method for 5G mmWave applications. The antenna dimensions are tiny, with a width of 17 mm and a length of 16 mm. The suggested antenna is constructed utilizing a Rogers RT5580 substrate with a thickness of 0.254 mm. The operating bandwidth of the antenna element is between 25.45 GHz and 44.25 GHz, including 5G frequency ranges. The results show a steady end-fire radiation pattern with a gain of more than 9.5 dBi across the whole frequency range. The suggested antenna's improvements and benefits for 5G specs, bandwidth, and small size are supported by the most recent study in the field. The suggested antenna element works well with large radio communities and 5G multi-input multi-output (MIMO) applications.
