Abstract:

Composite signals can be represented as a combination of multiple sinusoidal signals with varying frequencies, phases, and amplitudes. In general, these critical features can be manipulated by microwave components for different applications. As the indispensable part of most microwave components, microwave resonators play a significant role in functional circuit designs. Single resonance (single mode) circuit in one order or higher orders have dominated industry’s usage of microwave circuits and systems. For high-power applications such as base stations, satellite communication, and aerospace communication, conventional SMR waveguide components have the advantage of achieving high performance and meeting required precision performance specifications. However, their bulky circuit volume and high fabrication cost hinder their implementation in many space-constrained scenarios. There is a need to tackle these challenges by means of a novel approach. MMRs, with more than one resonant mode in a single resonator, have been investigated by several research groups over the last decade. Compared to SMR, besides the merits of circuit miniaturization, low-loss, and low-cost, MMR has an inherent advantage of diverse topologies with better out-of-band signal attenuation, due to the generation of additional transmission zeroes (TZs). In addition, MMR provides more design freedom and flexibility in function integration, which might not be possible using single mode resonators. The main contents are as follows: 1. Cavity filtering magic-T and its integrations into balanced-to-unbalanced (B2U) power divider (PD) and diplexing power divider. 2. Single-band and dual-band filtering antenna arrays (FAAs) based on high-order mode resonators. 3. In-band full-duplex (IBFD) filtering antenna arrays based on high-order mode resonators for narrowband and wideband applications. 4.
