Abstract
The dielectric loaded cavity for high frequency filters consists of a metal container housing s dielectric block held in position by supporting plates, that also sustains coupling and tuning elements. This invention provides broadband filters, small in size and with low losses. Its high symmetry structure considerably reduces the energizing of spurious modes and furthermore facilitates the design using automatic calculation procedures, on the basis of accurate electromagnetic models.
