Design of a low‐profile, dual‐mode, dual‐port and single‐band antenna with very high isolation for wireless body area network applications

In this study, a simple and compact antenna structure with dual-port dual-mode operating in single-band is proposed for wireless body area network. This composed of rectangular ring patch antenna, which shorted the outer edge to generate an omni-azimuthal radiation pattern. pattern desired on-body communication level. A substrate integrated waveguide cavity-backed slot also located at centre provides broadside off-body The fabricated measured. measured results are good agreement simulated ones. mutual coupling between two ports less than −40 dB about 13.5 better that previous works.
