    摘要： Lower-limit frequency reflection characteristics of a horn antenna (2) are improved even though element spacing, of less than or equal to one wavelength, is a spacing at which grating lobes do not occur in an antenna radiation pattern. The horn antenna (2) includes a horn antenna (2) and a conductor grid (1) that divides an aperture A (4) of the horn antenna (2) in a grid pattern and that electrically connects to an inner surface of the horn antenna (2) at the aperture A (4) of the horn antenna. Width of the conductor grid (1) in a direction orthogonal to a horn antenna aperture plane differs from electrical length of the path of the horn antenna (2) of the conductor grid (1) portion at the frequency of power supplied to the horn antenna (2).

    摘要： A dielectric hollow antenna apparatus includes a hollow inside tapered rod (e.g., a waveguide) with a flat section and a cap. The antenna further includes a feed through section, a feed pin, and a metal flange. A low loss dielectric material fills the hollow rod that protrudes beyond the metal waveguide to form a radiating element. The radiating element is designed in such a way to maximize radiation and minimize reflections over the antenna bandwidth. The feed through section reduces internal reflection and the waveguide is designed to include a rectangular waveguide that support a propagation (TE01) mode and the waveguide then transitions to a circular waveguide that supports another propagation (TE11) mode. The antennas can be employed for radar level gauging and withstand high temperature and possesses a small diameter that permits the antenna to fit in small tank nozzles.
