RLSA antennas were suggested by several researches as Wi-Fi antennas in addition to panel antennas. Therefore, this paper researched the possibility of this suggestion. We used the size of an available in market 16 dBi panel antenna (225 mm 2 ) as the size for our developed RLSA antenna. Based on this size, we developed 60 RLSA models using extreme beamsquint technique and simulated them. We then chose a best model with a best performance. The best model was then fabricated and measured. The simulation and measurement results show that the developed RLSA antenna has better performance compared to the 16 dBi panel antenna in term of gain (0.25 dB higher) and bandwidth (570 MHz wider). The RLSA antenna also tested as antenna for a Wi-Fi device and it showed good performance.

This research developed a small RLSA antenna that mimics the specification of a Wi-Fi antenna that is available in markets, which is a Back Fires 17 dBi LAN antenna. This research used the size of the back fires antenna as the size for the RLSA antenna. Base on this size, we designed and simulated 71 RLSA antenna models. Among them, we chose a best model and fabricated its prototype. We measured the prototype and found that the measurement result fits the simulation result, thus verifying the correctness of the antenna model. Furthermore, we analysed that with the same size, our RLSA antenna has better performance compared to the back fires antenna, in term of gain (0,53 dB higher), and in term of bandwidth (1075 MHz wider). We also found that our RLSA antenna is lighter and thinner compared to the back fires antenna. We also test the RLSA antenna in real condition for indoor and outdoor communication link. The test showed that the RLSA antenna can performs properly.

“…Moreover, Purnamirza used two-cavity layers to enable reflected signals eliminate each other [26] and also introduced extreme beamsquint technique in another study to efficiently radiate power through slots to achieve a significant reduction in signal reflections [29]. Purnamirza successfully implemented this technique to design several small Wi-Fi RLSAs for market needs [30][31][32][33]. The recent development of RLSA is a cutting technique which is designed to minimize the size of small RLSA antennas [34][35] and multibeam RLSA antennas [36].…”

RLSA antennas normally have a single beam produced by slots installed on their radiating element. A technique was, therefore, introduced in this study to optimally design multibeam RLSA antennas. This involved the utilization of the antennas' background to radiate signals by installing slots on it just like the radiating element to ensure the creation of multibeam after which the effects of this method such as signal flow disturbances and gain reduction were discussed. Moreover, 105 multibeam RLSA models were designed and simulated to verify the technique developed after which a prototype of the best model was fabricated and measured to verify the simulation. The result showed it is possible to obtain multibeam antennas with similar symmetry in terms of beamwidth and directions. Furthermore, the gain recorded for beams 1,2,3, and 4 was 8.28 dBi, 6.28 dBi, 6.38 dBi, and 8.18 dBi respectively, and were averagely about 6 dB lower than the value for single beam RLSA antennas, therefore, they suit the theory of beam splitting. The antennas were also found to have more than enough bandwidth and good reflection coefficient and the technique's validity was verified by a strong agreement between the simulation and measurement results.
