Design of the Dual Linear Polarized Radiation Element Using a Open-Ended Ridge Waveguide

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A Design Approach for Dual-Polarized Multiband FSS using Self-Similar Fractal Element

In this paper, fractal FSS has been designed using recursive technology and this frequency selective surface (FSS) acts like a multi band-reject filter. The proposed design has been investigated theoretically using Ansoft Designer® software in which the reflection and transmission band has been predicted by the method known as Method of Moment. In comparison to the reference square patched Freq...

Dual Band and Dual Polarized Substrate Integrated Waveguide Slot Antenna

A new dual band and dual polarized slot antenna is designed at x band, using longitudinal and transverse slots on the broad wall of the substrate integrated waveguide. The two resonances are completely apart in a low cross polarization level at both sets. antenna has a minimum radiation efficiency of 80% in both bands.

Novel Circularly Polarized Substrate Integrated Waveguide Slot Antenna By Using A Polarizer Technique

circularly-polarized antenna is built based on new SIW(substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (RHCP) and fabricated in two separate layers. A broadband impedancebandwidth of 13.9% and a RHCP axia...
