The antenna exhibits dipole antenna-like behavior with wide-band impedance matching from $213-700$ MHz. Plasma is sustained by $0.9$ W of RF input power at $100$ MHz and the gas pressure is strategically controlled at $500$ mili-Torr. The simulated $S_{11}$ is verified against the available experimental data and further antenna parameters are extracted. The proposed ESA shows dipole-like radiation pattern with a radiation efficiency of $16\%$ at $700$ MHz. The performance metric for ESAs, the Chu-limit, is exceeded by this antenna with the $Bandwidth\times Efficiency$ reaching $0.168$ with a $ka$ of $0.5571$.The findings from this letter demonstrate the practicability of using COMSOL Multiphysics as a tool for predicting plasma behavior and antenna performance while the boundary conditions for all the coupled physics are respected.
