In this paper, a simple and novel Ultra-wideband (UWB) micro strip patch antenna is developed with a compact dimension (15 x 12 x 0.8) mm3 and low complexity. This design improves a number of microwave circuit features, including wide bandwidth, and achieved optimum gain, among others. The proposed antenna is intended to operate in the frequency range from 22 to 29.6 GHz, the antenna is mounted on a Rogers RT Duroid 5880 compact dielectric substrate with a thickness of 0.8 mm and a dielectric constant of (εr = 2.2). Elliptical slots have been added in the simple capsule shape radiating patch to achieve wideband performance for the proposed antenna structure. The proposed antenna, with a frequency range from 22 to 29.6 GHz, has a wide bandwidth of 7.6 GHz. As a result, the proposed antenna design is small and appropriate for higher frequencies. The results of the simulation confirm that the antenna model is appropriate. In comparison to conventional patch, performance parameters like reflection coefficient, gain, and VSWR has improved. The EM simulator Ansoft HFSS v.15.0 performs all essential simulations, and a thorough comparative analysis based on the current antennas is performed. The suggested antenna has good impedance matching at |S11| < – 10 dB, VSWR is less than 2 and peak gain is 6.08 dBi at 24 GHz. Since the suggested antenna resonates at millimeter wave frequencies, it can be used for 5G applications. These excellent results in terms of tiny size, UWB operating band, high gain, good impedance matching, desired radiation features suggest that the proposed antenna would be a decent choice for 5G mm-wave applications.
