Abstract
A flexible spiral antenna or flexible antenna array element includes a flexible dielectric medium, a spiral element including a first arm and a second arm. The spiral element includes a liquid metal material and is disposed in the dielectric medium. The flexible antenna element also includes a first flexible meta surface layer disposed in the dielectric medium. The antenna can be or be part of an ultra-wide frequency band antenna or antenna array.
