The substrate integrated waveguide can easily be integrated with planar microwave circuits. Antennas designed on this transmission line have a planar structure, and can be fabricated by a standard PCB technology, so they are suitable for mass production. This paper presents the results of an investigation of leaky wave antennas designed on a substrate integrated waveguide. The interest is given to...
This work presents a novel class of filters in substrate integrated waveguide (SIW) technology, based on a multilayered configuration. The peculiarity of these filters is the presence of additional poles and zeros, due to the resonant slot etched in the common metal layer between two dielectric substrates. In this way, a filter with two mono-modal cavities, coupled by a resonant slot, exhibits a frequency...
A low cost, fully planar tunable oscillator with a low phase noise, high DC-RF conversion efficiency for C-band is presented in this work. The proposed oscillator utilizes a novel complementary coupled resonator based on substrate integrated waveguide (SIW) that has a broad tuning range of 8.84% relative bandwidth, and thereby achieves a continuous tuning oscillation range from 4.85 GHz to 5.1 GHz,...
