A mm-wave Circularly Polarized Wristwatch Dielectric Resonator Antenna for Off-Body Communications
A mm-wave circularly polarized, CP, wristwatch dielectric resonator antenna (DRA) is proposed as a potential candidate for off-body applications in the 24-34GHz frequency range. The proposed design has been excited using a cross slot aperture etched on the cylindrical ground plane and fed using a microstrip line. The antenna has been simulated using CST microwave studio in free space and on-wrist using equivalent elliptical cylindrical dielectric layers with parameters that are equivalent to those of the wrist. The DRA offers an impedance bandwidth of ~27%, a gain of 9.42 dBic, and a circular polarization bandwidth of ∼14.7% in free space. When placed on the wrist, the antenna achieved impedance and CP bandwidths of ~19% and 10.6%, respectively. To the best of our knowledge, this is the first attempt on a studying a mm-wave wristwatch DRA.
