A Design of Compact Radial Line Slot Array (RLSA) Antennas ... A Design of Compact Radial Line Slot Array (RLSA) Antennas for Wi-Fi Market Needs Teddy Purnamirza1, *, Donny Kristanto 1,andImranM.BinIbrahim2 Abstract—This paper proposes a compact Radial Line Slot Array (RLSA) antenna for 5.8GHz Wi-Fi devices, which meets market needs. Various small RLSA antenna models with radius of 140mm, were A linearly polarized radial line slot antenna - IEEE Journals ... 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.

Spiral Slotted Microstrip Antenna Design for 700 MHz Band… This work describes the design and implementation of spiral slotted microstrip antenna.To determine the performance of the design parameter, as impedance, resonance frequency, radiation pattern, and polarization, HFSS simulation software has been used and experimental tests under an... Antennas for Low Power Wireless Applications A suitable antenna design is critical to achieving adequate range and link robustness in a low power wire-less radio system. The best antenna choice will depend on the nature of the application - hand-held, wall mounted, etc. Also, the antenna must be tuned to present a suitable impedance match to... Radial Line Slot Antenna in Ka-band for Space Uses Radial line slot antennas (RLSAs) are planar slot array antennas for circular polarization on oversized parallel plate radial waveguides. RLSA has been well known as a high gain, high efficiency antenna operating in high frequency ranges because of its low loss property of the waveguide. Slot Antenna Design for Ultra | Wide slot Antenna – …

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.

Radial Microstrip Slotline Feed Network for Circular Mobile ... antenna for mounting on a car roof [3] and a X-Band radial line slotted waveguide antenna [4] have been demonstrated. In the above electronically scanned printed
