Design of a high-gain wideband microstrip antenna with a stepped slot structure

This paper focuses on an antenna with a stepped slot structure. The paper analyzes the impedance and radiation characteristics of this type of antenna and designs a high-gain wideband antenna that operates in the L-band and S-band. The simulation results show that the antenna has a comparatively high gain, wide impedance bandwidth and beamwidth in the entire L-band and S-band, and can thus be used in the design of antenna arrays.
