This letter presents a novel and simple feeding technique for exciting orthogonal
components in a wide-slot antenna. In this technique, a rectangular bracket-shape parasitic …

The design method for a standing-wave series slot array antenna with 45°-inclined linear
polarization in the Ka-band is presented. The proposed 16× 8 planar slot array antenna …

In this article, a broadband circularly polarized (CP) reflectarray (RA) is presented. A Ka-
band multilayer-CP RA antenna is designed and further validated through measurements …

This study attempts to attain a broad bandwidth (BW) from a simple and low cost dual
linearly polarised structure. The unit cell is a patch loaded with three concentric slots: a …

RLSA antennas normally have a single beam produced by slots installed on their radiating
element. A technique was, therefore, introduced in this study to optimally design multibeam …

Two wideband circularly polarized (CP) antenna arrays are proposed, based on sequential
rotation (SQR) arranged polarization grid and specially designed wideband full-substrate …

In this letter, a low-sidelobe level (SLL) circularly polarized (CP) beam-scanning array
antenna based on a double-layer rotated structure is proposed for Ku-band satellite …

In this paper, a radial line microstrip antenna array (RL-MSAA) for linear polarization is
designed. Stacked microstrip antennas (MSAs) with a stub element in the upper parasitic …

A 94-GHz dual-polarization low-sidelobelevel slot array antenna is proposed. A 2x2-slot
cavitybacked subarray is adopted as the basic unit of the array. A high-isolation orthogonal …

A wideband circularly polarized (CP) reflectarray (RA) antenna using rotational symmetrical
crossed dipoles is presented. This is the first time investigating coupled crossed dipoles as …
