Abstract

Nowadays, the evolution of wireless technologies with high speed and fast connectivity are really needed because of demands by the users. The fifth generation (5G) cellular network was introduced where to meet these demands. The centre frequency of 28 GHz where chosen because it is located in the range of Ka band frequency based on IEEE standard which are from 26.50 GHz to 40.00 GHz for 5G mobile communication system by designed and developed for Radial Line Slot Array (RLSA). The RLSA is well known as a simple structure antenna, low cost and high efficiency. This RLSA antenna can produces of three polarizations which are linear, circular and elliptical polarized. This project is more focusing on the linear polarized of RLSA using “Flame Retardant” FR-4 as the substrate and 1.13 for permittivity value which is the summation of the value of substrate with the air gap. The Computer Simulator Technology (CST) Microwave Studio has be used as antenna simulator for doing simulation with carried out the result before start the next step of fabrication and measurement of the antenna. The specifications of the result between simulation and measurement must meet for the antenna on directivity; radiation pattern and return loss were noted as comparison between simulation and measurement in the lab. In conclusion, the RLSA antenna is achievable to provide high gain which is more than 20.00 dBi and radiation pattern at 28.00 GHz for cavity thickness with air gap technique of h = 2.5 mm shows the better for point to point communication and potentially can be operated on 5G mobile communication system.
