Analysis and Design of an Antenna Array with a Cosecant Radiation Pattern Based on the SIW Structure

Phase shifter based on the substrate integrated waveguide technology

“…Unlike [8] where via post are used to create the phase shift effect, more compact means presented in [1,7] uses alternative rows of vias within the SIW to create the phase shift. This article continues on from previous research [4], which focused on the design of a feeding network based on the SIW technology for a phase antenna array operating at frequency band X (from 8.85 GHz to 9 GHz). In [4], the experimental hybrid structure of the feeding network has been designed.…”

The power divider part is based on the SIW technology and the phase shifter part is based on the microstrip line technology.…”

“…The geometry of the structure as shown in Figure 3 allows for the propagation of the dominant TE10 mode inside the substrate within the two rows of metallic vias which ensures that the electromagnetic field does not emit radiation into the environment. This is particular useful in event where several microwave circuits are placed close together, for example, in phased array antennas which consist of several feeding network [4].…”

“…The motivation of research [4] was to design the feeding network with ease of construction and very low value of undesired radiation. This article presents another way of feeding an array network with the implementation of a SIW phase shift using air holes.…”
