A H-shaped Slotted Circular Patch Antenna for Sub-6 GHz Applications

The main focus is to represent a H-shaped slotted circular patch antenna (SCPA) for sub-6 GHz. The antenna resonates at 4.02 GHz and covers a large bandwidth of 2640.8 MHz (3.3198 GHz to 5. 9606GHz). It also exhibits very good reflection coefficient profile (-34.749 at 4.02 GHZ), VSWR (1.0373 at 4.02 GHz) and radiation efficiency (average =94%) which ensures the antenna would be practically usable within the intended Sub-6 GHz operating band. The proposed SCPA is printed on low dielectric material Rogers RT5880 having thickness of 0.79 mm. The area of the SCPA is 34$\times$ 30m
²
. It possesses an impedance of (50.651-jl.7257) $\Omega$ which is close to 50 $\Omega$. The current distribution and gain of the SCPA is also good. Therefore, the designed SCPA can be considered as a good competitor for Sub-6 GHz applications.
