A novel compact monopulse cavity-backed substrate integrated waveguide (SIW) antenna is
proposed. The antenna consists of an array of four circularly polarized (CP) cavity-backed …

A mode-matching method is proposed for the accurate and fast analysis of structures
composed by metallic and dielectric posts in a parallel-plate waveguide environment. The …

In the last decades, the use of electronic components operating at microwave frequencies
has grown tremendously. Commonly known applications are related to satellite-based TV …

This paper presents an efficient analysis of a substrate integrated waveguide (SIW) single‐
layer hybrid ring coupler (rat‐race) for millimeter‐wave and microwave applications. The …

In this paper we discuss the design and measurement of a set of metallic post-wall
waveguide components for antenna feed structures. The components are manufactured on …

In the last decade, post-wall waveguides have emerged as an interesting building block for
(antenna) feed networks because of their potential low losses, low costs, ease of …

1. Introduction heconcept of substrate integrated waveguides was proposed [1] to overcome
the drawbacks of conventional rectangular waveguide and has drawn much attention, for it …

During the past five years, dielectric and metallic post-wall waveguides (PWWGs) have been
analyzed at TNO Defence, Security and Safety, using both an integral equation approach …
