abstract = "Dense, wideband and high-gain Resonant Cavity Antenna Arrays (RCAAs) are presented in this paper. Two array topologies (comprising square & radial configurations) made out of a Transverse Permittivity Gradient Superstrate (TPGS) are specifically investigated for meeting ETSI Class-2 specifications. Their boresight performance is characterized on the basis of peak directivity, 3dB directivity bandwidth, and most importantly the far-field radiation pattern envelope (RPE) masks. In comparison to a 9 × 9 square array, a radial array (having 91 elements) is shown to achieve the peak directivity of 37 dBi with a 3dB directivity bandwidth of more than 20{\%}. In addition, the radial array demonstrated the potential of satisfying minimum ETSI Class-2 antenna requirements with appropriate RPEs up to 50° and SLLs as low as-17 dBi.",
