In this paper. a wideband circularly polarized cylindrical shaped dielectric resonator antenna (DRA) with simple microstrip feed network has been designed and investigated. The proposed design uses dual vertical microstrip lines arranged in a perpendicular fashion to excite fundamental orthogonal hybrid HExIIδ and HEyIIδ modes in the cylindrical DR. The Phase quadrature ... https://www.ldartstudio.com/product-category/hair-colour-retouch/
