We have recently studied radiation from a slot array antenna using a rectangular waveguide fully filled with a ferrite slab [5]. This paper presents an investigation on radiation from a slot array antenna, which is partially filled with ferrite. The Fourier transform and mode matching method will be used to obtain a fast convergent series solution. Antennas: The Slotted Waveguide Antenna (Planar Array of ... The problem arises because the physical dimensions along the E-plane is much shorter than that along the H-plane (the slotted waveguide is long but thin). In general, a longer antenna (or longer array) produces a narrower beam. This problem can be circumvented by arranging slotted waveguides in parallel, as shown in Figure 1. Figure 1.

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. A cavity-backed coplanar waveguide slot antenna array 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.

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- Slotted Waveguide Array Antenna | Anil Pandey
