The ability to utilize a single cylindrical dielectric resonator to realize a multi-functional device is presented. Simultaneous excitation of multi-independent modes of a single dielectric resonator is used for filtering and oscillating as well as radiating purposes is discussed. A design of a dielectric resonator antenna in a polarization filtering cavity for dual function applications is studied where a cylindrical dielectric resonator is enclosed by a hypothetical resonant cavity that acts as a shielding for the resonating mode while transparent for the radiating mode. A possible application of this device is a receiving antenna at the frequency of the radiating mode and can incorporate a local oscillator operating at the resonant frequency of the resonating mode.In this presentation, ANSYS HFSS – a full-wave 3D FEM electromagnetic simulation – is used to perform simulations of the dielectric resonator.
