Abstract: This study shows an enhanced octagonal circularly polarized (CP) patch antenna, This one appropriate for mobile applications, such as wireless applications, especially for WIMAX, and 5G mid-band. A single-port excitation approach is utilized to obtain the intended outcome. The substrate used is Rogers RT/duroid 5880 with a relative permittivity of 2.2 and a low loss tangent (0.0009). The antenna’s dimensions are optimized with the final design measuring 32 × 35 × 1.67 mm3. To generate the circular polarization a square slot is cuted, and two stubs are inserted in the opposite corners of the ground plane. A good result is achieved, for the reflection coefficient, we have a bandwidth (< -10 dB) of 1.29 GHz (2.8 GHz-4.09 GHz) and the bandwidth of the Axial ratio (AR) below 3 dB is 500 MHz (3.33 GHz−3.83 GHz). (CST) and (HFSS) softwares were used to calculate all obtained results. This microstrip antenna has a tiny dimension, it is simple to fabricate and has a lightweight, it has high performance, such as a wide band of the reflection coefficient of 1.29 GHz, also, its circular polarization makes it ideal for mobile applications, particularly WIMAX and 5G mid-band.
