A stable design of coaxial adaptor for radial line slot … A new design of feed for radial line slot antenna (RLSA) is presented. For better impedance match to the waveguide the effect of the various feed parameters is analyzed and their design sensitivity is studied. This paper emphasizes the advantages of using feed with a funnel below the connector entry... (PDF) Low-cost monopulse radial line slot antenna The antenna is a radial line slot antenna, with the slots placed on the upper plate in concentric rings. The radiation element is a slot pair, designed forThe authors propose a design procedure and an analysis method for radial line slot antennas. Several prototypes have been fabricated to validate...
Simulation results showed that dielectric constants have great effect in the design and overall radiation performance of the RLSA antennas. At 12.5GHz resonant frequency, higher dielectric constant records a drop in both efficiency and directivity of the RLSA antennas.
A radial line slot antenna (RLSA) is a nonresonant multimode waveguide slotted array. To improve the power handing capacity, we design a radial line slow wave structure which replaces a A Reconfigurable Radial Line Slot Array Antenna for … A Reconfigurable Radial Line Slot Array Antenna for WiMAX Application 55 achieves a higher gain in comparison to the divisive broadside pattern. Figure 8 depicts the 3D simulation of the far field radiation patterns of the proposed antenna which is aligned with the measured radiation patterns as shown in figure 6 and figure 7. However, the A linearly polarized radial line slot antenna - IEEE

found to be an effective feed network for single layer radial line slot array antenna. However, further studies with the feed probe terminated in none disk shaped elements is required. Thus; termination with conical and frustum shaped elements are studied for a single layer radial line slot array antenna at 28 GHz in this paper. The sensitivity

A linearly polarized radial line slot antenna - IEEE Abstract: 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. Radial line slot array (RLSA) antenna design for point to

COMMUN., VOL.E82{B, NO.1 JANUARY 1999 165 PAPER A Full-Wave Analysis of a Complete Model for a Radial Line Slot Antenna Tetsuya YAMAMOTO y, Student Member, Jiro HIROKAWAy, and Makoto ANDO , Members 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).
