Development of Rubber Substrate for More Robust Flexible Wearable Antenna at 2.4 GHz Application

In this work, a flexible microstrip patch antenna has been designed to be working at 2.4 GHz using rubber as the substrate material with permittivity of 3.0 and loss tangent of 0.02. The proposed antenna has been designed to achieve a good result of reflection coefficient, vswr, gain, directivity, and antenna efficiency at the selected operating frequency. The design of rectangular microstrip flex...
