Abstract: In this paper, a novel circular polarization switchable slot-ring array antenna is proposed. The proposed antenna consists of a 2 × 2 slot-ring array antenna and a orthogonal feed circuit.

Abstract: A novel near-field (NF) radio sensing antenna array design framework is proposed, where the circular antenna arrays are exploited to be compatible with the propagation of the spherical ...
