Phased array antenna metamaterial based design operating in millimeter wave for 5G mobile networks

In the following couple of years, an alternative for the 4G and its derivatives like the LTE-A is inventible. The demands and challenges must be envisaged and addressed to meet the desired objectives of the upcoming 5G mobile networks which are resembled by significant increasing in capacity, improved data rate, low latency, and better quality of service. To achieve these objectives, radical enhancements and improvements have to be made in cellular network architecture and the antenna configuration that is used for this purpose. This paper presents the results of a 5G cellular network phased array antenna with millimeter wave beamforming at 28Hz. A microstrip structured antenna on a metamaterial substrate that performs as a leaky wave, in which, it has a composite cascaded right left handed transmission line configuration 32 unit cells. The main beam is tuned via varicaps with gain changing between 5dB to 6dB during scanning.
