Abstract: Slotted waveguide antenna (SWA) arrays offer clear advantages in terms of their design, weight, volume, power handling, directivity, and efficiency. For broad-wall SWAs, the slot displacements from the wall centerline determine the antenna's sidelobe level (SLL). Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). ADVANCED DESIGN AND ANALYSIS OF UWB U-SLOT MICROSTRIP PATCH ...
The waveguide slot antennas we will be discussing have longitudinal slots in the broad face of stan-dard rectangular waveguide, parallel to the length of the guide. Figure 7-1 is a photograph of a typical waveguide slot antenna, with a total of 12 slots, six on each side, in WR-90 X-band waveguide for 10 GHz operation.
For the slot antenna, the resonant conditions arise from the circumference of the slot, which is proportional to the guided wavelength [6]. The input return loss level and the resonant frequency of the proposed design will vary with total length L and width W of the substrate. Slot Loaded Square Microstrip Patch Antenna for Dual Band ... Introduction. The simultaneous use of slots and short-circuit vias, allows to obtain an FR from 1.3 to 3 depending on the number of vias as shown in [32]. In this paper, we have proposed a design to obtain dual band performance via mode modification in square microstrip patch antenna with dimension 30 mm 30 mm. A design procedure for slotted waveguide antennas with specified ... Slotted waveguide antenna (SWA) arrays offer clear advantages in terms of their design, weight, volume, power handling, directivity, and efficiency. For br. Slot Antennas - QSL.net Waveguide slot antennas, usually with an array of slots for higher gain like Figure ..... We can summarize the design procedure for a waveguide slot antenna: 1.
136 mm for a straight slot is slightly increased to 139 mm for In an effort to further decrease the total area occupied by S-slot at 600 MHz for a substrate with and thickness the antenna, the slot configuration was altered from its stan- of 2.54 mm.

practical design procedure to design U-Slot antenna and provide physical insight into the design using full wave analysis methods. This research work focuses on developing a novel scheme to design wideband U-Slot antenna. To validate the design technique antenna is fabricated and measured results are compared with the simulated to assess the Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear. Design of Modified Bowtie Antenna for Wireless Applications
Following this procedure, a slot antenna is designed in the frequency band of 5-8 GHz for the purpose of gain enhancement over the entire operating band. Length of the slot determines the first resonating frequency and these slots radiate like a half wave dipole whose length is half of the...

Design of Substrate Integrated Waveguide Multi-band Slots Abstract—In this paper, the design of slots array antennas based on Substrate Integrated waveguide (SIW) has been analyzed and simulated. A waveguide slot antenna has a vertical row of slots along the length of a vertical waveguide, with the Design of Fractal slot Antennas for WLAN and WiMAX The objective of this project is to design and simulate the Koch and Gasket patch (microstrip) monopole fractal antenna [9-10]. The behavior and properties of these antennas are investigated. 1.3 SCOPE OF THE PROJECT. The scopes defined for this project are as follows: • Understanding the antenna concept.
