NDLI: Sensing probe for 3–6 GHz microwave imaging systems

Content Provider	IET Digital Library
Author	Lee, Kwang Jae Kim, Jang Yeol Son, Seong Ho Lee, Jongmoon Jeon, Soonik
Abstract	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.
