Patent
Dual polarized array antenna
TL;DR: In this article, a planar array antenna with radiating elements characterized by dual simultaneous polarization states and having substantially rotationally symmetric radiation patterns is considered, where a ground plane is positioned generally parallel to and spaced apart from the radiating element by a predetermined distance.
Patent
Dual-polarized antenna
TL;DR: In this article, a dual polarized antenna with at least one dual polarized radiator device comprises a reflector (3) and longitudinal or transverse webs (9, 11) provided at least on its longitudinal side and/or on its transverse side.
Patent
Dual polarized array antenna with central polarization control
TL;DR: In this article, a planar array antenna with radiating elements characterized by dual simultaneous polarization states and having substantially rotationally symmetric radiation patterns is considered, and a central polarization control (18) network is proposed to control the polarization states of the received signals distributed via the distribution network.
Patent
Miniature multi-branch patch antenna
TL;DR: In this paper, a miniature multi-branch patch antenna suitable for operating in the 1 GHz to 100 GHz frequency range is presented, and a communication system using the same is described.
Patent
Spatial filtering surface operative with antenna aperture for modifying aperture electric field
TL;DR: In this article, a spatial filtering surface (100) includes a dielectric substrate (106) and a plurality of spaced, geometrically configured, resonant elements (104) positioned on the substrate, forming concentric rings that attenuate any electromagnetic radiation passing there through a different amount.
