Conventional researches about network harmonic suppression generally assumed the network was linear and individual at various frequencies, which ignored the coupling relations of nonlinear loads. This paper studies coupling characteristics by matrix model. Through simplifying matrix model, a novel online control method of active power line conditioners (APLC) was proposed.
A novel E-plane 3 dB directional coupler with enhanced out-of-band rejection has been proposed and developed in multilayer HMSIW topology. A continuous coupling slot is etched in the conductor layer at the broadwall of HMSIW. Periodic ginkgo leaf slots are etched on top layer of HMSIW to realize a pass-band combining with high-pass characteristics of HMSIW. Coupling takes place through the long, offset...
A novel high-performance millimeter-wave multilayer dual-mode filter is developed based on the substrate integrated waveguide circular cavity (SICC). The filter with two or three SIW circular cavities has been designed for Ka-band application. The multilayer dual mode filter has been firstly realized only by adjusting the coupling aperture located in input/output port and between layers. The position...
A novel E-plane 3 dB directional coupler has been proposed and developed in multilayer HMSIW topology. A continuous coupling slot is etched in the center conductor layer at the magnetic-wall of HMSIW. Design process is introduced based on the even-odd mode theory. As a promising technology, the developed HMSIW E-plane coupler inherits those merits of low profile, low insertion loss, low lost and good...
A novel HF fishbone antenna with V-shape dipoles is introduced. Long V-shape dipoles instead of short linear ones are used as elements to increase the directivity. NEC-2 (Numerical Electromagnetic Code Version 2) is involved to numerically evaluate the radiation characteristics of this new fishbone antenna with two different arm lengths, 12 m and 20 m, respectively. Parameters such as open angle of...
