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. Micro strip , Slotted Rectangular Waveguide Array and ... Slot offset 9.2 mm Rectangular waveguide wide side 94 mm Fig. 5(c). 3D Radiation pattern for the slotted rectangular waveguide array antenna The patch-rod antenna has been simulated and analyzed using The slot array antenna is designed with 8 numbers of slots by using a substrate copper with specifications 5.8x107 S/m Ansys HFSS V14.0. US8957818B2 - Circularly polarized waveguide slot array ... A circularly polarized waveguide slot array includes first and second waveguide sections, the first waveguide section extending along a longitudinal axis, and including an antenna element for transmitting or receiving a circularly polarized signal. Slot array antenna and plasma processing apparatus - US 2006 ... A slot array antenna, comprising: a power-feeding waveguide for feeding microwave power; and a plurality of rectangular radiating waveguides connected to a plurality of windows which are disposed along the longitudinal direction of the power feeding waveguide, so as to guide the microwave power from the plurality of windows to the outside of the 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. TWO-DIMENSIONAL ARRAY OF ANTENNA GEOMETRY AND … Key words: wideband antennas; phased arrays; coplanar waveguide; rectangular slot INTRODUCTION In applications where size, weight, cost, performance, ease of installation, and aerodynamic profile are constraints, low-profile antennas such as microstrip and printed slot antennas are required. Printed slot antennas fed by a coplanar waveguide Slotted Waveguide Array Antennas | SAGE Millimeter Our Slotted Waveguide Array Antennas take advantage of the low loss nature of the waveguide and printed circuit manufacturing process to offer high performance and loss cost solutions. Waveguide Slot Array Antennas - Springer
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
Waveguide slot array antenna with EBG high-impedance surface ... Abstract: A method of raising the front to back (F/B) ratio on the pattern for the slot array antenna of rectangular waveguide using electromagnetic band-gap (EBG) structure as a high-impedance ground plane is studied in this paper. An example antenna is designed and measured. Design of Slotted Waveguide Array Antenna Fed by H-Plane ... 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 (Planar Array of Slots)
