In this paper, a new family of low profile, high quality factor cavity resonators, termed distributed resonators, is introduced. Initially, the theory of operation of the proposed distributed resonator is presented with reference to two, three and four coupled resonators. Based on this, a further-improved arrangement of resonator elements is proposed, leading to an increased inter-resonator element coupling, which results in low frequencies of operation and high quality factors. It is shown that the height of the individual resonator can be controlled by the number of resonator elements and can be, almost, arbitrarily low.View Original Article
