“…The structure will also produce back radiation and parasitic radiation at higher frequencies which will affect the DRA's radiation pattern [3]- [5]. Since the Substrate Integrated Waveguide is enclosed by metal plates and feeding fields are restricted in the substrate, it has an exceptionally good shielding between exterior and interior, thus avoiding radiation loss and parasite radiation of the feeding structure [6].…”

In this paper a laminated waveguide fed DR Antenna is investigated. It can use for moderate power military applications. Cylindrical DRA is excited by two closely spaced asymmetric longitudinal slots on the broad wall of the laminated cavity are responsible for producing three different frequency bands. Parametric study of slots has been done with the help of commercial software ANSOFT HFSS. All the bands have sharp rejection. The final model of the antenna is simulated, fabricated and experimentally measured. Measured results are in quite accordant with design results. SIW feeding structures have small losses, moderate power handling capacity, low costs, compact sizes and can be seamlessly integrated with planar circuits. At all the bands 9.76 GHz, 10.53 GHz and 11.8 GHz resonant frequency, the antenna shows 56 MHz, 160 MHz, and 250 MHz impedance bandwidth (for VSWR<2) with 6 dB,6.2 dB and 6.8 dB gain respectively. Simulated and measured results reveal outstanding performance with a cross-polar level of 29 dB lower than that of the co-polar level at 9.76 GHz, the cross-polar level of 32 dB lower than that of the co-polar level at 10.53, GHz, and similarly cross-polar level of 30 dB lower than that of the co-polar level at 11.8 GHz.

Abstract. This paper presented a designed coupler by using Rogers RO4003C with thickness (h) 0.508 mm and relative permittivity ( r ) 3.55. The four port network coupler operates in K-band (18-27 GHz) and design by using substrate integrated waveguide (SIW) method. The reflection coefficient and isolation coefficient of propose Substrate Integrated Waveguide (SIW) coupler is below than -10 dB. Meanwhile the coupler requirements are phase shift 90 o between coupled port and output. SIW are high performance broadband interconnects with excellent immunity to electromagnetic interference and suitable for use in microwave and communication electronics, as well as increase bandwidth systems. The designs of coupler are investigated using CST Microwave Studio simulation tool. This proposed couplers are varied from parameters that cover the frequency range (21 -24 GHz) and better performance of scattering (S-parameter).

In this article, a multi-resonance frequency scanning antenna with a Luneburg lens is designed. This antenna operates in the X-band and can achieve beam steering by changing the frequency in this band. The steering angle of the designed model is ±50 . This antenna is a good candidate for a wide range of telecommunication, automotive radar, and search radar applications. The advantage of this model over most of other works in this field is that just one multi resonant slot antenna in front of the Luneburg lens is used instead of several antennas and separate feed networks. This development leads to a compact structure with more straightforward and cost-effective fabrication. The antenna structure is based on a substrate integrated waveguide technology. Full-wave simulations are performed using the software of CST. The proposed model is designed and fabricated on Rogers RO4003C substrate with a height of 20 mils. A perforated Teflon sheet is designed and fabricated to approximate the inhomogeneous refractive index of the Luneburg lens.
