Horn antenna

A horn antenna module is provided. The horn antenna module includes a waveguide and an antenna cover. The waveguide includes a plurality of waveguide paths. The antenna cover covers one end of the waveguide. The antenna cover includes a plurality of protrusions and a bottom surface. The protrusions are formed on the bottom surface. The protrusions correspond one-to-one with the waveguide paths. Each protrusion has a top surface and a lateral surface. The lateral surface is located between the top surface and the bottom surface. The top surface is planar.

Horn antenna module and antenna cover thereof

A waterproof part for a feedhorn includes a first waterproof unit having a first interface for generating a first reflected wave and a first transmitted wave when a satellite signal incidents the first interface, and a second waterproof unit covering on the first waterproof unit and having a second interface for generating a second reflected wave and a second transmitted wave when the first transmitted wave incidents the second interface, wherein the first and second reflected waves are substantially out-of-phase to substantially cancel the first and second reflected waves.

Waterproof part

A waveguide orthomode transducer includes a waveguide including a first waveguide portion and a second waveguide portion placed along a transmission direction of radio signals, the size of an aperture of the second waveguide portion smaller than the size of an aperture of the first waveguide portion, a first probe disposed at a first position, a second probe disposed at a second position, a third probe disposed at a third position, and a fourth probe disposed at a fourth position, wherein at least two of the first position, the second position, the third position, and the fourth position are located in the same plane perpendicular to the transmission direction of the radio signals.
