Radial line slot antenna design

By author

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.

[0009] This radial line slot antenna has many advantages, and is expected to play an important role as a millimeter wave band antenna for mobile communication, including radio LAN, in the near future. [0010] The name of the radial line slot antenna is often simply referred to as “RLSA”, which stands for Radial Line Slot Antenna. Radial Line Slot Array (Rlsa) Antenna Design At 28 Ghz Using ...

the antenna aperture in this case. A radial line slot antenna (RLSA) for surface-wave-coupled plasma (SWP) is a promising candidate to this end. A novel slot arrangement in the aperture, consisting of densely arrayed transverse slots, was fabricated and tested.

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.

Using a slotted line, you could also measure an unknown frequency by measuring the distance between the voltage peaks and noting that the distance is 1/2 wavelength. Here's some slotted line equipment that we found recently on Ebay (none of which sold!) Hewlett Packard C17540 HP 816A.
