High-gain Slot Antenna on a Grooved Structure with à Frequency Selective Surface

Résumé

This paper presents a high-gain antenna for non-contact measurement systems around the frequency ~26GHz. The proposed antenna consists of a slot antenna on a metallic grooved structure with a single frequency selective surface. A small size and improved gain performance are the key objectives of this design. To achieve these two objectives, we use an optimization procedure based on a global algorithm. Both simulation and optimization are carried out by means of a full-wave electromagnetic simulation tool. Afterward, a prototype of the proposed antenna has been manufactured in order to verify their performances. More than 15dB of gain is obtained over the operating frequency range, with approximately 17dB at the frequency 25.5GHz. the small size and high-gain characteristics make this antenna very suitable for non-contact measurement, especially for short-range radar sensors.
