In this paper, one kind of subgrid technology using physical connection between different sizes cells is presented. Huygens method, one representation of equivalence principle, is used to solve the problems of filed values on the interface of different size cells. This new technology could solve electromagnetic problems for discontinuous structures. Numerical simulation of EWB structure is implemented.
A unequal power divider using anti-coupled and Microstrip Metamaterial Lines over a large bandwidth is proposed. The structure comprises anti-coupled power divider, followed by a +90° negative-refractive index (NRI) metamaterial (MM) phase-shifting line along the top branch, and traditional microstrip line along the bottom branch. The structure is used to deliver flexible variation of power division...
To adapt the miniaturizing and integrating development requirement of ESM & RWR, This paper designs an UWB Suspended Substrate Stripline(SSS) highpass filter using Ansoft HFSS and Design software, and the test results is given.
Microwave U-slot patch antenna with a shorting pin is suitable for ultra wideband (UWB) communication system. This article introduces the simulation and the experiment of the UWB antenna model which increases its impedance bandwidth and gain bandwidth. The antenna bandwidth is expanded by the diversification designed for the shorting pin and the feed pin. The simulation model and the test result are...
A new ultra-wide band-pass FSSs suitable for high frequency and wideband applications is presented. The band-pass structure consist only double layer FSSs and one kind of dielectric material with high dielectric constant. By designing three different arrangements, transmission characteristics of wideband and ultra-wide band in large oblique incidence are realized.
This paper presents novel Hilbert fractal shaped complementary single split ring resonator (CSSRR) with a tunable transmission zero realized by negative effective permittivity of it and multi-band property attributes to Hilbert fractal geometry. Transmission characteristics of several CSSRR cells have been assessed by using full-wave electromagnetic simulation. Also miniaturization performance as...
