Bandwidth-Enhanced Electrically Large Microstrip Antenna Loaded With SRR Structures

摘要

In this letter, microstrip-line-slot feed patch antenna element and array with electrically large property (ELP) are designed and discussed. Periodic three-dimensional split-ring resonator (SRR) structures are introduced as inclusions to realize the ELP. By tuning the structure parameters, their effective permittivity (epsilon(eff) < 0) and permeability (u(eff) > 0) could meet the requirement of -1
