This paper presents a design of origami mode and frequency reconfigurable quadrifilar helical antenna that can reconfigure itself to operate at different modes (i.e., normal or axial mode) and different frequencies. This antenna is also collapsible and therefore, it is very suitable for satellite and space applications.
