摘要：

Metamaterials are a popular choice to increase the gain of microstrip (patch) antennas, but their transmissivity is notably constrained to <= 100 MHz bandwidth in the super high frequency (SHF) band. Sub-classes of metamaterials, including superstrates, multi-resonance rings, and frequency-selective surfaces, enhance the gain of a wideband rectangular patch antenna (RPA), but only at the resonance frequency. We propose a 1 GHz modified split ring resonator (MSRR) that expands the bandwidth gain enhancement range without increasing the size of the overall antenna structure. The study investigates the impact of altering MSRR dimensions and how they affect the magnetic field and the induced current over a wide bandwidth. The MSRR's impedance bandwidth is optimized to be three times broader than conventional SRR, resulting in a peak gain improvement of 5 dBi when placed on top of a wideband RPA.
