Abstract

From the viewpoints of cost-effectiveness and fabrication accuracy, the self-injection locked NRD guide Gunn oscillator using a metal rod resonator was investigated at 60GHz, where the supporting method for the metal rod resonator hasn´t been established. With this in mind, the metal rod resonator supported by the dielectric pieces which have a high mechanical strength and an easily fabrication was examined in this paper. First, the resonant characteristics of the PEEK (Polyether-ether-ketone) materials to use as the dielectric pieces were measured. Next, the eigenvalues of the PEEK resonator were calculated, and then the dielectric constants of the PEEK were estimated at nearly 60GHz. Finally, the lowest mode and the first higher mode resonators supported by the PEEK were designed and the resonant characteristics were calculated.
