A Capacity Reconfigurable Multimode Origami MIMO Antenna

In this work, a receconfigurable multimode Multiple-Input-Multiple-Output (MIMO) antenna is proposed. This antenna is composed of seven identical dual band elements each simultaneously operating in two orthogonal modes. The antenna is implemented on an accordion origami support structure which allows the inter-element spacing to be uniformly varied. This spatial reconfigurability results in a 15% and 13% variation in capacity for the first and second modes, respectively. With this antenna, the capacity, gain, and physical size can be optimized for real-time operational requirements.
