Directive Multiband Antenna Based on Rectangular Loop Array and Dumbbell-Shaped Slot Radiator

In this article, a combination of rectangular loop array and slot radiator for multiband applications is presented. The antenna is configured by arranging, concentrically, a set of rectangular loop radiators excited by electromagnetic coupling provided by a dumbbell slot. The size of the loops is ca...
