The width of the patch influences the radiation efficiency and the antenna's input impedance. It is calculated using the target resonant frequency ( ) and the substrate's dielectric constant ( ϵrepsilon sub r

In this paper, we presented a comprehensive review of patch antenna design principles and introduced a patch antenna calculator, a design tool that simplifies the design process. The calculator takes into account the design parameters, including resonant frequency, substrate material, and patch dimensions, and calculates the required patch dimensions and feed location. The example design demonstrates the effectiveness of the calculator in designing a patch antenna for a wireless communication system. The calculator takes into account the design parameters,
