First, the flexible substrate is electromagnetically characterized and then the design is carried out using CST microwave studio.

One of potential applications of this flexible RF planar antenna is in microwave imaging and non-destructive testing (NDT) of various structures and media, where the antenna can be closely fitted around the test objects and may act as sensor. It is low cost, light weight, flexible and easy to integrate with other electronic devices.
