摘要：
This article presents an accurate full analytical model to assess the impedance response of a proximity-coupled microstrip patch antenna (PC-MSPA). An improved formulation of the patch resonant frequency is used to calculate the quality factor, resonant resistance, and feeding circuit parameters of the antenna. The proposed model also assesses the PC-MSPA impedance response while considering the fabrication constraints. For the validation of the proposed model, at first, the antennas are simulated for S-, C-, and X-bands. Then, two prototypes are fabricated and measured. The proposed model predicts the antenna resonant frequency and impedance bandwidth with less than 1% error.
