MULTI-BAND CDR SMART ANTENNA FOR 5G APPLICATION: MID-BAND (7 GHZ) EXTENSION AND VISION 2030

Recently, a new analysis of the spectrum needs of 5G networks across low-, mid-, and high-bands has been released by Global System for Mobile Communication Association (GSMA) [1]. Actually, GSMA's recommendation is concerned with the extension of the existing spectrum or search for a new and adequate band for the business and consumer services demand, which is part of vision 2030. Mid bands for 5G applications are found in the range of 1 GHz to 7 GHz in which lower mid-bands and the upper mid-bands are in use for rural areas or deep-indoor coverage in cities. However, an extension of another 7 GHz of the 5G spectrum is needed, so that telecom operators can provide enhanced mobile broadband (eMBB) in a dense urban environment [2]
