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 ... Antennas: The Slotted Waveguide 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.
Compact Two-Layer Slot Array Antenna for K-Band Applications ... A novel two-layer slot array antenna based on substrate integrated waveguide (SIW) technology was designed and simulated. Unlike already reported SIW slot arrays, the present design achieves considerable reduction in size by using a feed waveguide placed underneath the slot array and coupled through slanted slots to branches of the array.

wavelength whereas slot width is one twentieth of free space wavelength. Excitation port is placed at the end opposite to the shorter end of waveguide. The details of the design parameter of the waveguide, slot dimensions and their positions are summarized in TABLE 1. The proposed linear array antenna was designed and
Antennas: The Slotted Waveguide Antenna Slotted antenna arrays used with waveguides are a popular antenna in navigation, radar and other high-frequency systems. They are simple to fabricate, have low-loss (high antenna efficiency) and radiate linear polarization with low cross-polarization.These antennas are often used in aircraft applications because they can be made to conform to the surface on which they are mounted. Non-Resonant Slotted Waveguide Antenna Design Method ANTENNA DESIGN I n this paper a non-resonant slotted waveguide antenna design method is present-ed.

In order to confirm the usefulness of this method, a non-resonant waveguide array antenna with longitudinal slots cut in a broad 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.

would only contain one type of slot or array, although multiple slot/array types may be used if the desired antenna performance cannot be realised using one type. Although the current SWASS development program is limited to standard rectangular waveguides, alternative waveguide cross-sections such as circular, elliptical and half-elliptical Design of a Two-Element Antenna Array Using Substrate ... The design of a two-element antenna array using the substrate integrated waveguide (SIW) technique and operating at 10 GHz is presented. The proposed antenna array consists of two SIW phase shifter sections with two SIW slot antennas. The phase shifting is achieved by changing the position of two inductive posts inserted inside each element of the array.
