In this paper, a compact single-feed crossed-dipole antenna backed by a near-field resonant parasitic (NFRP) element is proposed to enhance the bandwidth and front-to-back (F-B) ratio of the electrically small antenna system. The NFRP element is designed to not only act as a reflector, but also to generate an extra resonance with circularly polarized (CP) radiation for the antenna system. The extra...
A broadband electrically small antenna with directive circularly polarized radiation is presented. It is composed of a compact single-feed crossed dipole driver, which is backed by a near-field resonant parasitic (NFRP) reflector to achieve the directive radiation pattern. The NFRP reflector is designed to generate extra resonances and minimum axial ratio (AR) points in the antenna system. These features...
