PROJECT TITLE : Split Slots Array for Grating Lobe Suppression in Ridge Gap Guide. ABSTRACT: A frequency-scanning antenna array of nonresonant slots with uniform slot field distribution is designed using the ridge gap waveguide (RGW) technology. Slotted Waveguide Array Antenna | Electronics Design… Slotted antenna arrays used with waveguides are a popular antenna in navigation, radar and other high-frequency systems.A waveguide is a very low loss transmission line. It allows to propagate signals to a number of smaller antennas (slots). Each of these slots allows a little of the energy to...

Babinet’s Principle | Waveguide Slot Antenna… Waveguide slot antennas are often used as omnidirectional microwave antennas. According to Watson4, the slot array was invented in 1943 at McGill University in Montreal. Unique features of these antennas are horizontal polarization and omnidirectional gain around the azimuth.
4.2 Array of Slotted Waveguide Antennas with two Dielectric Lenses. The array is created by duplicating the antenna.These values are all slightly longer than the designed focal length of 85mm. The electric field was also plotted across the y directionat various z distances as shown in figure 5-12...
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 Gap Waveguides - Springer of two analytical approaches used so far in the prediction of propagation performance of groove gap waveguide and ridge gap waveguide. One of the approaches is the spectral domain approach in which Green’s functions of the considered structure are determined. On the other hand, in the second approach, IEEE Xplore: IEEE Transactions on Antennas and Propagation - ( ) A novel fully on-chip antenna based on a metasurface fabricated in a 180-nm BiCMOS process is presented. Inspired by the concept of high impedance surface (HIS), this metasurface is not used as a reflector below an antenna as commonly done. Instead, it is used as a radiator by itself.
