The future communication system is a fifth generation (5G) wireless communication. This communication system requires an antenna with a simple design, low traffic (high channel capacity), high gain, low cost, low power consumption (high battery life) and easy to fabricate in MMIC. The rectangular patch antenna (RPA) is a simple design, low cost, low power consumption and easy to analyze and fabricate. However, it has been affected by narrow bandwidth and single resonating frequency. That means, it has low channel capacity (high traffic) and used for the single task. These problems have been overcome by modifying the RPA. Two parallel slots have been placed on the RPA then it seems like English letter E. This modified RPA or E-shaped patch antenna (ESPA) will have the impedance bandwidth (wideband) or get a multi resonating point for enhancing channel capacity or multitask. The proposed antenna has been designed with optimized slots length and width, and position of inset fed to achieve for a wide bandwidth or a dual band with investigating the behavior of the current paths on the patch. HFSS 14V software uses to design and simulate RPA and ESPA at 28 GHz with the FR4 epoxy substrate material. Finally, the optimized proposed antenna’s results of dual-band and wideband have been resonating at frequencies of 29.12 GHz and 31.35 GHz, and impedance bandwidth 3.2 GHz respectively, and observing radiation pattern, gain and directivity are also observed.
