A series-fed loop antenna array, deployable by means of a scissors-type stretchable mechanism is presented. The antenna topology uses a continuous conductor with proper size to produce in-phase vertical currents that creates a highly directive pattern. The design methodology and simple guidelines for obtaining desired input impedance, gain and front-to-backloberatio (FBR) are presented. A wire prototype was realized as proof of concept, demonstrating input impedance and radiation characteristics according to expectations.
