A Compact Broadband Planar Inverted-F Antenna with Dual-Resonant Modes
In this paper, a compact broadband planar inverted-F antenna (PIFA) with dual-resonant modes (TM1/2,2 and TM3/2,0) is proposed for 5G applications. By loading a pair of horizontal slots on the patch, the TM3/2,0 mode can be shifted downward and combined ...

We propose exciting two modes concurrently inside a reltron's modulating cavity to increase the microwave power generated. From the harmonic components of the beam, we demonstrate that a multiharmonic beam has a higher peak and steeper gradient compared to a single-harmonic beam.

This Letter proposes a balanced dual‐mode substrate integrated waveguide (SIW) filter for the first time. Based on dual‐mode square SIW cavities, perturbation vias, and balanced ports, the quasi‐elliptic differential mode response with improved selectivity as well as high‐performance common mode suppression can be obtained conveniently.

Design of Multi-Band Filters Using Parallel Connected Topology [PDF]
This paper presents the design of multi-band filters using parallel connected topology. The resonator in each branch is the dual-mode resonator which provides two resonant modes per passband for miniaturization.
