Busuioc, and S. Safavi-Naeini. Full Article PDF (511 KB) Abstract: A novel slot array antenna with two layers of substrate integrated waveguides (SIW) is presented for millimeter-wave wireless applications. US20090066597A1 - Substrate Integrated Waveguide Antenna ... A substrate integrated waveguide (SIW) slot full-array antenna fabricated employing printed circuit board technology. The SIW slot full-array antenna using either single or multi-layer structures greatly reduces the overall height and physical steering requirements of a mobile antenna when compared to a conventional metallic waveguide slot array antenna.

A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz.

Antennas: The Slotted Waveguide Antenna An example of a slotted waveguide array is shown in Figure 1 (dimensions given by length a and width b) Figure 1. Basic geometry of a slotted waveguide antenna. As in the cavity-backed slot antenna, each slot could be independently fed with a voltage source across the slot. However, (especially for large arrays) this would be very difficult to ... SLOT ARRAY ANTENNA USING FOLDED WAVEGUIDES Benito Sanz ...

Non-Resonant Slotted Waveguide Antenna Design Method ANTENNA DESIGN I n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od. In order to confirm the usefulness of this method, a non-resonant waveguide array antenna with longitudinal slots cut in a broad

To Reduce Side Lobe Level of Slotted Array Antennas Using some efforts are using probes near the slots [7, 8], using iris exciting [9], using asymmetric ridge waveguide [10, 11], using partially dielectric filled waveguide [12], and using wiggly-ridge waveguides [13–15]. In this article, side walls of a hol-low waveguide are made nonuniform to reduce side lobe lev-
