A broadband rectangular waveguide to substrate integrated power divider for hybrid beam forming networks is presented. Rectangular symmetric E-plane irises are used realize a multi-section matching network. circuit and full-wave design procedure described adopted synthesize three with one, two, irises, progressively increasing the bandwidth exceeding state of art in last two cases. Three proof-...

A four-way power divider/power combiner using substrate integrated waveguide (SIW) and microstrip lines is proposed and investigated. The proposed power divider consists of a double-layer substrate with a bottom layer including an SIW T-junction and a top layer including a microstrip network. This microstrip network consists of a modified Gysel power divider which provides a high isolation betw...

Abstract This paper proposes a hybrid scanning antenna architecture for applications in mmwave intelligent mobile sensing and communications. We experimentally demonstrate suitable Wband leaky-wave antenna prototypes in substrate integrated waveguide (SIW) technology. Three SIW antennas have been designed that within a 6.5% fractional bandwidth provide beam scanning over three adjacent angular...

A novel single-cavity dual mode substrate integrated waveguide (SIW) filter with mixed source-load coupling (MSLC) is presented. By using an interdigital slot-line (ISL) to introduce mixed coupling between source and load, the proposed filter with only one cavity could have three transmission zeros which can be controlled flexibly. Under the circumstances, the filter exhibits better frequency s...

Hexagonal dual-mode cavity and its application to substrate integrated waveguide (SIW) filter are presented. The hexagonal SIW resonator which can combine flexibility of rectangular cavity and performance of circular cavity is convenient for dual-mode bandpass filters design. By introducing coupling between source and load, the filter not only has good selectivity due to two controllable transm...

This paper presents a novel compact dual-band and dual-polarized complementary split-ring resonator (CSRR)-fed substrate-integrated waveguide (SIW) cavity-backed fractal patch antenna for wireless energy harvesting and communication. The proposed antenna is composed of a Giuseppe Peano fractal radiation patch with a backed SIW cavity. To enhance the bandwidth and minimize the dimensions, the CS...

In this paper Substrate Integrated Waveguide-based filtenna operating at Ku band is proposed. The model designed on a low loss dielectric substrate having thickness of 0.508 mm and comprises shorting vias along two edges the walls. To realize bandpass filter, secondary are placed close to primary vias. dimension position carefully analyzed for frequencies. fabricated Roger RT/duroid 5880 perfor...
