Designing the Four-Tooth-Shaped Microstrip Antenna for Wi-Fi Applications

A monopole microstrip antenna with the radiator having two pairs of rectangular teeth of different sizes is considered. The influence of the size of the teeth and the position of the cutouts between them on the electrodynamic characteristics of the antenna at the first and second resonance frequencies is studied. Based on the results of the analysis, the approach is proposed to optimize the electrodynamic characteristics of this antenna type for given parameters. The practical application of this approach in the designing the four-tooth-shaped dual-band antenna for Wi-Fi applications is shown.
