This letter presents a miniaturized probe-fed elliptical microstrip patch antenna (PF-EMPA) targeting the 8.50-10.55 GHz band for radiolocation applications. The proposed design is composed of an elliptical patch inserted into an elliptical slot. In order to achieve our goals and control the impedance matching, we adjusted the offset distance from the elliptical patch to the side of the elliptical slot. As results, this work presents the characteristics of a new microstrip patch antenna operating at 9.845 GHz (9.650 – 10.222 GHz) providing higher gain value (more than 6 dBi), and an impedance matching bandwidth of around 5.75%. The performance of the structure is simulated by electromagnetic simulator CST Microwave Studio. Details of the obtained results are presented and discussed.
