چکیده
circularly-polarized antenna is built based on a 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 axial ratio of 0.5ghz have been obtained under the conditionof less than vswr ≤2 and axial ratio≤ 3 db, respectively

متن کاملDual 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.
متن کاملWLAN Substrate Integrated Waveguide Filter with Novel Negative Coupling Structure
A fourth-degree Substrate Integrated Waveguide (SIW) crossed coupled band pass filter for WLAN band is designed by using a new negative coupling structure. It consists of two U shape microstrip lines on top and bottom planes with via holes at the center of them. This paper investigates the phase characteristics of negative and positive coupling structures and their effects. The design, fabricat...

planar slot antenna using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. SIW has all the advantages required for a small size antenna package: Lowcost, high-performance and ease of integration. The SIW antenna with tapered microstrip-SIW transitions are integrated and synthesized on a single substrate. This structure is designed with Finite Element Method (FEM) using...
