The Radial Line Slot Array (RLSA) Antenna is known for its good characteristics such as low profile, low cost, aesthetically pleasing, ease of installation and simple structure. RLSA antenna normally applied polypropylene as a dielectric material in the middle of the radiating plate and ground plane. This research is focusing on applying FR4 as a dielectric material. The prototype has been simulated, fabricated and measured. The measurement obtained a -15dB of return loss, 11.5dBi of directivity gain and 5% antenna bandwidth.

Abstract-This paper proposes a compact Radial Line Slot Array (RLSA) antenna for 5.8 GHz Wi-Fi devices, which meets market needs. Various small RLSA antenna models with radius of 140 mm, were designed using extreme beamsquint technique. The models then were simulated to result in a best model. A prototype of the best model was then fabricated and measured to verify the simulation. The measured parameters are: a gain of 18 dBi, bandwidth of 1 GHz, beamwidth of 20 • , and mainlobe to sidelobe ratio of 15 dB, which meet antenna specifications for market needs. The prototype was tested as an antenna for a Wireless Fidelity (Wi-Fi) device in order to show its performance. The test showed that the prototype worked properly. Lastly, we compared the size of the prototype with the average size of various antennas available in markets. We found that the prototype had the advantage of small size and flat, with similar performance.

This article presents a wide band linearly polarized beam squinted radial line slot array (RLSA) antenna at 5.8‐GHz band. The open ended air gap technique was used to broader the bandwidth, reduce the antenna size but maintain the high‐performance characteristic. The antenna implemented radiating slot design with diameter of 200 and 1.6 mm hybrid FR4 and 8‐mm open ended air gap for dielectric height. The antenna also successfully fabricated and performed a good result. The measured results show a wide 38% of bandwidth with 16 dBi gain at 5.8‐GHz frequency. The beamwidth obtained below 15° for E and H plane. The research found a wide band RLSA antenna can be achieved using air gap technique and will be a potential candidate for future point to point application for fixed broadband wireless access. © 2014 Wiley Periodicals, Inc.
