Abstract—In order to improve the efficiency, reliability, and accuracy during fabrication of antenna in 5G regime of frequencies, a Double-Material Substrate (DMS) Cylindrical Surrounding micro-strip fed Patch Antenna (CSPA) has been designed for use in 2.4/5.8 GHz WLAN, 2.5/5.15 GHz WiMAX wireless standards, 5.9 GHz Intelligent Transportation Society (ITS) band (5.85-5.925 GHz) and middle band of 5G technology (2.3 GHz ~ 2.4 GHz and 2.5 GHz ~ 2.69 GHz). The proposed antenna addresses the negative effect of dimension inaccuracy caused by the high permittivity substrate material used in CSPA. The antenna was designed, simulated, and thoroughly analyzed on the basis of the radiation pattern, surface current distribution, and Q factor. Findings reveal that the DMS CSPA showed a worthy radiation pattern and Q-factor of 3.62 and 2.31 at 2.68 GHz and 5.55 GHz bands, respectively. The radiation plots of simulation results present the angular width values between 45⁰ ~ 104⁰, showing a wider coverage area with minimal sidelobe level between -4.4 dB ~ 11.9 dB for the E-planes and H-planes at both resonance frequencies.
