description	Nowadays, a wireless communication technology are moving towards fifth generation (5G) which consist all the previous generation technologies. Radial line slot array (RLSA) antenna became very popular since the weight is light and ease of installation besides the ability to carry high speed signal with high directivity characteristic and the potential of beam steering and beam shaping. Furthermore, this RLSA antenna can perform three polarizations such as linear, elliptical and circular. The aim of this project is to design, simulate and fabricate the new closed ring resonator (CRR) structure which operating at 28 GHz frequency. The objectives of this research are to study different characteristic of FR4 and RT Duroid 5880 materials and enhanced the return loss (RL), Su of the hybrid RLSA antenna air gap with RT Duroid 5880 performances at 28 GHz by introducing the CRR structure. Besides, to study the performance of hybrid air gap with RT Duroid 5880 RLSA antennas with and without the presence of a layer of the superstrate CRR structure. Those designs were simulated and assist by Computer Simulation Technology (CST) Microwave Studio Software and tested with the network analyzer. The result for a gap ll I 4 of hybrid air gap with RT Duroid 5880 with a layer of the superstrate of cicumference CRR structure at 28 GHz had 19.430 dBi of gain and-15.044 dB reflection coefficient. The gap value of a layer superstrate had been increased to ll I 2 and the reflection coefficient improved to - 17.191 dB with gain increased to 20.020 dBi. The hybrid air gap with RT Duroid 5880 RLSA at ll I 2 shows a good for 5G point to point communication system.
