Paper Based Conformal Antenna

This paper presents the design of a conformal antenna on one of the most attractive, flexible, low cost, easily available substrate i.e. paper for 5.2 GHz wireless local area network (WLAN) band. The extraction of the substrate characteristics such as the dielectric constant and dielectric loss is performed using the cavity perturbation technique. The flat substrate is bent with different radii and the effects of curvature are studied and analyzed in terms of return loss, bandwidth, gain, and radiation pattern.
