چکیده
A compact two-port feeding circuit that supports a dielectric resonator (DR) element is presented for applications requiring polarization diversity. The L-band structure consists of cylindrical DR can generate right-handed circular (RHCP), left-handed (LHCP), and linearly polarized radiation. dimensions have been optimized considering relative constant ε r = 27, the entire (the DR) has 9 cm ×9 ×2 (or about 0.3 λ xmlns:xlink="http://www.w3.org/1999/xlink">0 ×0.3 ×0.07 at lower operational frequency range). Radiation by originates from four orthogonal HE xmlns:xlink="http://www.w3.org/1999/xlink">11δ modes are excited radial slots etched out ground plane (all underneath printed on top an FR-4 substrate.

Abstract—An ultra-wideband (UWB) planar monopole antenna integrated with a narrow-band (NB) cylindrical dielectric resonator antenna (DRA) is presented. The proposed antenna consists of a UWB monopole excited by a coplanar waveguide (CPW) transmission line, acting as a ground for a DRA excited by a slot. The mode HEM11δ is excited in the NB DRA. To validate the concept of integration, an antenn...
