A coaxial feed for multiband antenna for a multiband antenna includes: a tubular high-band (HB) waveguide, the HB waveguide including an outer conducting surface, an inner HB conducting surface, and a HB aperture defined by the inner HB conducting surface; a tubular low-band (LB) waveguide disposed coaxially around the HB waveguide, the LB waveguide including an outer feed surface, an inner LB conducting surface, and an annular LB aperture defined by the inner LB conducing surface and the outer conducting surface of the HB waveguide; and an annular high-band (HB) choke located in the outer conducting surface of the HB waveguide, the HB choke being axially offset from the HB aperture.

A multi band antenna system for transmission and reception of electromagnetic signals in a low-profile dual reflector configuration with position-controlled main-reflector, and fixed sub-reflector and feed horn. An added linear slide of the main-reflector with respect to the sub-reflector synchronized with variable tilt angle of the main-reflector for compensation for the varied focal length in the main-reflector to the beam due the varied main-reflector tilt. The system achieves a beam elevation of 10° to 100° (full elevation), minimum gain variations over the full elevation travel, swept volume as per ARINC 791 (e.g. Boeing Radome or Airbus Radome), and can be used to meet wide-Tx/Rx bands requirements.

An aperture-sharing method for a dual-band aperture-shared antenna. By means of the method, a first dielectric substrate is arranged directly above a floor, a second dielectric substrate is arranged between the floor and the first dielectric substrate; a first meta surface, a first radiation ring, a second radiation ring and a second meta surface are arranged in a first quadrant to a fourth quadrant of the top surface of the first dielectric substrate; a fourth radiation ring, a fourth meta surface, a third meta surface and a third radiation ring are arranged in a first quadrant to a fourth quadrant of the bottom surface of the first dielectric substrate; first high-frequency antenna elements are symmetrically arranged on the top surface of the second dielectric substrate; and second high-frequency antenna elements are symmetrically arranged on the bottom surface of the second dielectric substrate. Further disclosed is a dual-band aperture-shared antenna structure.

An antenna array includes one or more substrates and four individual antennas in a slant formation to improve radiation pattern independence. In various embodiments, a novel slanted antenna array configuration is disclosed where one of the four antennas is orthogonal to two of the remaining three antennas. In some embodiments, two separate substrates and a tapered dielectric spacer are used to provide a larger variety of slant formations.

A high power top mounted slotted coaxial broadcast antenna for broadband multi-channel applications is achieved via applying phase cancelation through multiple feeds. The effect that external transmission line feeds have on the circularity of the azimuth pattern is reduced using parasitic tubes near the surface of the slot apertures.
