Design of miniaturized frequency Selective surface for Electromagnetic shielding

Abstract

newline Over the past ten years, mobile users have multiplied dramatically newlineover the world. From first-generation (1G) to fifth-generation (5G) mobile newlinecommunication, the number of users and available features have increased newlinesignificantly. The range of spectrum increases as the generation of mobile newlinecommunication increases, thus, making the 5G utilize a spectrum range of newline600MHz - 6GHz for Long Term Evolution (LTE) and 24-86 GHz for newlinemillimeter (mm) wave bands. A number of additional bands, including 3300- newline3400 MHz and 10.0-10.5 GHz in Region 2, will be considered for newlineInternational Mobile Telecommunications (IMT) under Agenda 1.2 by World newlineRadio Conference 2023 (WRC-23). The implementation of IMT creates newlinehindrances for novice users who wish to operate in this frequency band. As a newlineconsequence, the International Amateur Radio Union (IARU) has conveyed newlineits objection to the International Telecommunication Union newlineRadiocommunication Sector (ITU-R) Working Parties and CITEL PCC II newlineregarding the allocation of 10.0-10.5 GHz for IMT. newline
