Millimeter Wave Frequency Reconfigurable Antenna for 5G WLAN

This paper presents the comparative analysis of most demanded future 5G millimeter wave reconfigurable wireless generation networks antenna. The four Models of antennas presented are designed on 60GHz resonant frequency, standardized unlicensed band for future 5G Wireless local area network (WLAN) applications. The main Purpose of reconfigurable antennas are to remunerate the operation challenges of multi frequencies. The IEEE 802.11ad standard is used which is the requirement of 5G to meet the simulation results of the antennas. The variable resistors are used in the slotted microstrip patch antenna to achieve the reconfigurable mechanism. Four mode are presented, analyzed, simulated and their results are compared in this paper. The material of ground and patch used is the same material copper while the material used in substrate is named as Roger- Rt5880, relative permittivity 2.2(?r =2.2). The substrate material used is the same in all four models with changed in thickness of the substrate. The four models are simulated by using a software known as CST (Computer Simulated Technologv),
