Waveguide slot array antenne ontwerp

Planar slot antenna using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. SIW has all the advantages required for a small size antenna package: Low- cost, high-performance and ease of integration. The SIW antenna with tapered microstrip-SIW transitions are integrated and synthesized on a single substrate.

narrow-wall of waveguide. The slots etched on the narrow-wall must cut into the broadside for resonance, furthermore, the height of profile is increased compared with the other one. In this paper, a T-shaped waveguide is proposed and a 2 6 antenna array with metal fences working at 35 GHz is designed based on this new waveguide. Waveguide Slot Array Antenna Design, texas holdem poker oyunu indir, stef craps ghent university, blackjack fb A dual-polarization corporate-feed waveguide 16x16-slot array antenna was proposed and fabricated in the 60GHz band [1]. A 32x32-slot array antenna in the 120GHz band is designed to increase the operating frequency band and the gain. II. ANTENNA STRUCTURE A. Feeding waveguide There are two feeding waveguides in the antenna for the What is claimed is: 1. A slotted waveguide array antenna comprising a plurality of waveguide elements extending in a parallel side-by-side relation, each waveguide element having a longitudinal axis, a radiating side including a broad wall formed with a plurality of slots, a non-radiating side opposite to said radiating side, and a single asymmetric ridge in said non-radiating side

Waveguide slot arrays are widely used in radar and telecommunication applications, especially where high gain, increased power-handling capacity and compact dimensions are critical. Radar applications demand radiation patterns with sharp narrow main beams and very specific
