Study of a Conformal UWB Elliptical Monopole Antenna on Flexible Organic Substrate Mounted on Cylindrical Surfaces

This paper presents a conformal, compact, omnidirectional, elliptical monopole antenna on liquid crystal polymer (LCP) which is studied mounted on a cylindrical surface and is proven to operate equally well compared to its planar rival. The presented return loss, gain and radiation pattern measurements demonstrate that the characteristics of the antenna are not compromised when the antenna is mounted on cylindrical surfaces of various radii when the direction of curvature is in the transverse direction. The presented study shows that the proposed antenna can be optimized and tested in planar shape and still be trusted to operate equally well under conditions like in wearable electronics, where their planar condition cannot be guaranteed.
