This paper presents a design of X-band slotted waveguide antenna array that has a linear polarization and exhibits high directivity for a long-distance communication. Especially we present a procedure that is very useful in a realistic implementation. The design is validated by numerical simulation using HFSS, and measurement results will be presented in the conference presentation.
In this paper, the detailed antenna configuration as well as the feeding network design is presented in Section II. The antenna performance for linear polarization is shown in Section III, while the performance for circular polarization is given in Section IV. A novel polarization reconfigurable array antenna is proposed and fabricated. Measured results validate the performance improvement in port...
Helix antenna has distinguished characteristics of radiation. Depending on its designed structure, a variety of operations may be created including linear or circular polarizations, and omni- or directional patterns. The cost and complexity will increase significantly if it is employed in the applications of antenna arrays in the manufacture and RF circuit design. This paper proposes an alternative...
