The small size of patch antenna makes its application scenarios diverse, and its research is quite extensive. However, the calculation of the influence of the applied excitation source and operating band on the overall operation of the antenna is very complicated, and the related modeling is less. Therefore, a patch antenna model with dual input feed is constructed by COMSOL based on the finite element analysis method. After considering the reasonableness of the coaxial cable insulation medium setting, the geometry structure of the patch antenna with dual input end feeding is constructed. The balanced antenna uses two input feeds, so in the balanced system, the operational performance of the antenna is changed by adjusting the two input signal excitation, so the spatial electric field distribution of the patch antenna under different operating frequencies is explored by applying different external applied excitation sources. Finally, the electric field change law of patch antenna under different operating working conditions is compared and analyzed, and the way to analyze the antenna operating performance is summarized.
