A 60GHz Passive Repeater with Endfire Radiation Using Dielectric Resonator Antennas
Résumé
This paper presents the design of a 60GHz passive repeater endfire array using dielectric resonator antenna (DRA) elements. The proposed DRA antenna element is loaded with an open-ended microstrip line coupled through a slot, and the reflection phase is controlled by varying the length of this phase-delay line. Based on the working principle of reflectarray, two DRA elements with 180 o phase difference are selected with the aid of infinite periodic simulation model in HFSS. A 6x6 array is designed and simulation results demonstrate good endfire performance.
