文摘

The radiation characteristics of a stacked microstrip antenna geometry proficient of providing circular polarization along with wide impedance bandwidth is simulated by using IE3D software and later on this antenna was fabricated on FR-4 substrate with an air gap and testing is done in free space. The feed location, location of applied shorting pin and width of air gap introduced between driver element and parasitically coupled element were optimized to obtain best results. The measured impedance bandwidth better than 31.72% and axial ratio bandwidth close to 1.68% were achieved with the proposed geometry. The simulated and measured results obtained are in good match with each other.
