Dielectric notch radiator antennas with integrated filtering for 5G and IoT access

The development of dielectric notch radiator (DNR) antennas is described with integrated filters for 5G and IoT systems. The DNR is a type of tapered slot antenna (TSA) and is similar to the familiar Vivaldi antenna except that the length of the DNR is much shorter than a Vivaldi. The five step design process for the DNR is given and expands upon prior exponential taper design methods. The optimization and analysis of the microstrip to slot line section uses the finite element method (FEM). The DNR is used for a X-band antenna and line array. The single element simulated and measured return loss and antenna gain pattern are shown. The gain pattern for a four element line array is shown. The DNR is then used for an antenna system operating in the mobile phone and Wi-Fi bands. The antenna is integrated with filters to form a solution with application to 5G and internet of things (IoT) over Zigbee or Wi-Fi systems. The results demonstrate how the DNR antenna can be applied to solve wide band antenna design requirements where antenna length is an important design constraint.
