A Linearly Polarized Radial Line Slot Antenna.

Jul 8, 2014 High gain linearly polarized radial line slot arrays LP-RLSA suffer from remarkable degradation of the return loss. To overcome this drawback, this communication presents a novel LP-RLSA design obtained by the superposition of two spirally arranged circularly polarized RLSAs. Indeed, it benefits from the intrinsically low reflection coefficient proper of these circularly polarized spirally.

A single-layered radial line slot antenna RLSA is proposed for a direct broadcast from a satellite DBS subscriber antenna. It utilizes a radially outward-traveling wave and the aperture field is intolerably tapered if the uniform slots are used. Two novel techniques are applied. First, the slot design for uniform aperture field distribution is introduced. Second, the radial line is. A design for linearly polarized radial line slot antenna RLSA is proposed. A novel slot arrangement is presented which couples to the rotationally symmetric guided waves to produce a uniform aperture distribution with linear polarization. Basic characteristics were measured in the 12-GHz band on a model antenna. The radiation patterns indicate a reasonable cross-polarization level more than.

Use of Narrower Reflection-Canceling Slots to Design Linearly Polarized.

Jan 1, 2015 Abstract. This chapter presents the development history of radial line slot antenna. The antennas are used for circular polarized high-gain antenna in microwave and millimeter wave bands. Linearly polarized arrays are also provided by changing slot array arrangement. The linear polarization antenna radiates entirely in a single plane that contains the direction of propagation. Linear polarization antennas are subdivided into three categories: Vertically Polarized Antenna. A linear polarization antenna with an electric field directed perpendicular to the earth#x27;s surface is called a vertically polarized antenna.

Linearly polarised radial line slot antenna for highpower microwave.

The structure of a linearly polarized radial line slot antenna LP-RLSA for realizing dual beam operation is presented. The beam-tilt mechanism by the shift of feed point is explained. A model antenna with two feed points demonstrated the dual beam operation, and efficiencies of 33 and 45 were realized. This beam-tilt mechanism can be applied.

Dec 3, 2010 This letter investigates the performance of beam-tilting technique when applied to improve matching of linearly polarized radial-line slot-array antennas. The application of a full-wave analysis reveals a severe deterioration of radiation patterns even for small tilt angles. An iterative optimization procedure is proposed in order to restore the radiation performance in conjunction with the. 1 Introduction. Linearly polarised radial line slot antennas LPRLSAs were first introduced by Ando et al. [], who proposed the basic configuration.This type of antenna consists of a twofold radial guide with three plates separated a small distance apart, and fed at its centre of lower waveguide by a coaxial probe, so that only a transverse electromagnetic TEM mode can propagate.

A radial line slot array antenna is presented and experimentally discussed for a fifth generation 5G mobile communication system that resonates at the frequency of 28 GHz. Additionally, it is. The antenna radiates linear polarization at Ka band. Monopulse operation is obtained by a sum and difference network which is a compact eight-port comparator consisting of coplanar magic tees. The sum and difference network is waveguide structure whose loss is less than that of microstrip structure at millimeter wave lengths.

The beam shaping of a linearly polarized radial-line slot-array LP RLSA antenna is demonstrated with the production of a prototype with a broadened main beam pointed in an arbitrary direction. Apr 1, 2013 A planar linearly polarized radial line slot array RLSA antenna is proposed to achieve a high gain with improved impedance matching and suppressed cross-polarization levels at a 270-GHz band. The slot pairs of these antennas here are all arranged in concentric. Different slow wave materials or phase tuning structures are also added to alleviate grating lobes in radiation pat-terns. And low return loss can be improved by introducing a set of reflection cancelling slots. The second one is circularly polarized RLSA CP-RLSA antennas.
