A highly compact slot array antenna using substrate integrated folded waveguides (SIFW) is proposed in this\ud paper. The device has three key components: a non radiating SMA to standard waveguide transition, a power\ud divider from standard waveguide to folded waveguides, and slot arrays on the folded waveguide.

Antennas: The Slotted Waveguide Antenna

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 ...

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- 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.
