Abstract :
In this article, a dual-band aperture-coupled stacked circularly polarized microstrip antenna was proposed. This antenna consists of metallic square slot, metallic square patch, crossed aperture and microstrip feeding structure, making it easy to combine directional, circularly polarization and dual-band operation. The optimized antenna exhibits a good impedance matching within the UHF band (902MHz-928MHz) and ISM band (2.4GHz-2.5GHz). The experimental results of the constructed prototype are provided.
