Antenna that produces a radiation diagram of revolution around a geometric axis (X) and that has a maximum of radiation in a plane perpendicular to the direction of said axis X, the antenna comprising a conductive surface that forms a ground plane (300 ) of the antenna; a feeding wire (...
The designed antenna is composed of three right-angled slot radiators on the ground plane. The first two radiators are right-angled slots of similar scale which are added to generate circular polarization at 4.95 GHz, while the last one has been designed for linear polarization at 2.45 GHz. ...
In addition, dual‐sense circular polarization (CP) radiations are also achieved based on the method of using two orthogonal dipoles with different lengths. An antenna prototype is designed for wireless LAN applications and fabricated for validation. Measurements demonstrate that the proposed design ...

A CPW-fed dual-band slot antenna with circular polarization In this paper, a coplanar waveguide (CPW)-fed dual-band slot antenna with circular polarization (CP) is presented. In order to achieve CP characteristic, an asymmetric slot and F-shaped end patch are introduced to a conventional recta...
The proposed array antenna consists of a fed patch and four parasitic patches. Four switching diodes are loaded on the corners of the fed patch. The boundary condition of the fed patch is controlled by using the ON/OFF condition of the diodes, and the polarization angle of the array antenna...

摘要: PURPOSE: To maximize the aperture efficiency of an antenna by respectively separating slots VRn and VRn, and HRn and HRn by λg/2, offsetting the reflected waves of the slots in a radial waveguide, and reducing a reflective loss in a power feeding part....
Eutectic gallium﹊ndium liquid metal alloy is employed to tune the angle of linear polarization continuously. The antenna is feed at the center of a circular patch with a ring slot. The rotational symmetry of the antenna helps maintain the impedance and radiation pattern at different polarization ...
