Abstract: A phased array antenna system accommodating onto a platform for tracking a target moving relatively to the platform, the antenna system comprising a first planar active subsystem operable for receiving/transmitting an RF signal of a certain linear polarization direction and for selectively performing electronic scanning; a second, roll subsystem coupled to the active subsystem and operable for rotational movement of the active subsystem about a first axis perpendicular to a plane defined by the planar active subsystem; a third, elevation subsystem coupled to the second, roll subsystem and to a fourth azimuth subsystem, the azimuth subsystem defining a central axis of the antenna system and being operable for providing rotational movement of the first planar subsystem about the central axis, the elevation subsystem being configured to provide a certain angular orientation between the plane defined by the active subsystem and a plane defined by the azimuth subsystem, thereby allowing positioning the first planar active subsystem with respect to the target such that the linear polarization direction is substantially aligned with a linear polarization direction of RF radiation received and/or transmitted by the target.

Abstract: A variable phase shifter comprising a coupler including an input port, an output port, a through port and a coupled port and two conducting finite strips exhibiting equal lengths, the first conducting strip being movably coupled with the section of the coupler connecting the input port with the through port and the second conducting strip being movably coupled with the section of the coupler connecting the output port and with the coupled port, wherein displacing the conducting strip relative to the coupler, changes the phase of an output signal from the coupler, relative to the phase of a corresponding input signal into the coupler.

Abstract: A method of suppressing grating lobes generated in a radiating pattern of a phased array antenna, and a patch antenna element for use in the phased array antenna are described. The phased array antenna is formed from a plurality of symmetrical patch antenna elements spaced apart at a predetermined distance from each other. Each patch antenna element is configured for producing an asymmetrical radiation pattern. The antenna element includes a conductive ground plane, a radiating patch backed by a cavity and arranged in cavity aperture, and a feed arrangement. The patch antenna element is configured such that a dimension of the radiating patch along the E-plane of the antenna element is less than the dimension of the cavity aperture by a first predetermined value selected to provide an asymmetrical radiation pattern of the patch antenna element. To provide a required degree of the asymmetry of said radiation pattern, a dimension of the radiating patch along the H-plane should be less than the dimension of the cavity aperture along said H-plane by a second predetermined value.
