A sensing probe for medical imaging diagnostic systems is presented. The proposed probe consists of a double‐ridged waveguide (DRWG) filled with dielectric ceramic and an aperture with a tapered ridge. The DRWG is used to suppress higher‐order mode radiations in the rectangular waveguide. The proposed probe is designed for broadband sensing in an immersion liquid with a complex dielectric constant. The performance of the fabricated probe successfully covers the frequency band of 3–6 GHz. The probe suppresses higher‐order modes and provides symmetric and similar radiation patterns within the operating frequency range.
