A miniaturized antenna for surface‐to‐surface and surface‐to‐orbiter applications

Abstract

Abstract A folded Hilbert curve fractal antenna (fHCFA) which produces end‐fire radiation at the S‐band and broadside radiation at the Ku‐band without switches is presented. The measured gains/bandwidths were 1.2 dBi/10 MHz and 5.4 dBi/500 MHz at 2.3 GHz (S‐band) and 16.8 GHz (Ku‐band), respectively. This work offers a compact antenna design as a candidate for robotic applications in future NASA planetary exploration missions. © 2006 Wiley Periodicals, Inc.
