In the paper, a novel circularly polarized slot antenna was presented The antenna was designed for full integration into a 3D knitted fabric

It is shown that a properly designed, off- centered, microstrip-fed, moderately wide slot antenna shows dual resonant behavior with similar radiation Approximate formulas for the complex propagation constant and characteristic field configuration for dielectric‐filled traveling wave slot antennas are
