Abstract
In this paper, ultra wideband (UWB) low band wearable dual-polarized antenna array designs have been proposed for in-body to on-body communication channel of wireless capsule endoscope (WCE) application. Single element antenna, dual elements, four elements array are designed and compared in free space and in body proximity. Conformal design has been focused. Wilkinson power combiner has been employed with optimized designed substrate. Near field pattern measurement has verified that the proposed 1by2 antenna can achieve a good near field directivity as well as a dual-polarized performance compared with the standard monopole reference antenna in the near field transmission measurements with the circular polarized capsule antenna.
