A radial line slot antenna for an elliptical beam

By Guest

For comarison uroses, a unit cell without meandering and microstri line width equal to 50 m was also simulated in the same manner.

Radial line slot array antenna with broad beam is easily realized at frequencies in the lower part of super high frequency band. But emerging broadband mobile communication systems like the fifth generation target frequencies in the upper part of the band and beyond. Radial Microstrip Slotline Feed Network for Circular ...

A traditional radial line slot antenna (RLSA) is a high gain planar array. To improve the power handling capacity, we design a radial line slow wave structure whichThis high power microwave (HPM) RLSA is fed from a double-layered radial line waveguide to realize the directional radiation of the microwave.

Fig.1: Front View of Antenna In the present paper, an elliptical microstrip patch antenna for Ultra Wide Band applications has been designed. We are using elliptical patch because it provides comparatively larger bandwidth than others.

A Radial Line Slot Antenna for an Elliptical Beam - IEEE ... A radial line slot antenna (RLSA) with a quasi-elliptical aperture to create an elliptical beam is discussed in this paper. A simple feeding structure consisting of a coaxial feeder and two parasitic pins is designed to produce the feed pattern required for uniform illumination over the aperture.
