SLOT ARRAY ANTENNA USING FOLDED WAVEGUIDES Benito … A highly compact slot array antenna using substrate integrated folded waveguides (SIFW) is proposed in this paper. The device has three key components: a non radiating SMA to standard waveguide Slot Array Antenna using Folded Waveguides - kar.kent.ac.uk A highly compact slot array antenna using substrate integrated folded waveguides (SIFW) is proposed in this paper. The device has three key components: a non radiating SMA to standard waveguide transition, a power divider from standard waveguide to folded waveguides, and slot arrays on the folded waveguide. The antenna is built using two substrates aligned with conducting vias which makes the CORE
The resonant half-wavelength slot antenna is desirable because of its compact size; however, it has large input impedance, typically larger than 300 Ω, which makes it difficult to match to. This can be circumvented by using an offset microstrip feed or the folded slot antenna, which
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 ... A highly compact slot array antenna using substrate integrated folded waveguides (SIFW) is proposed in this paper. The device has three key components: a non radiating SMA to standard waveguide ... 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
The design of a 112-element millimeter-wave waveguide slot array antenna to reduce the grating lobe level is presented. A hybrid-phase feeding technique combining a cophase feed and an alternating-phase feed is applied to facilitate the suppression of grating lobes. In addition, a stepped feed waveguide and offset coupling slots aligned in a line are employed to realize a tapered aperture
