Problems solved by technology

Reference 1 does not disclose in detail the degree of improvement in the radiation pattern brought about by the corresponding horn antenna, making it difficult to quantify the degree of performance improvement
Even so, structural simplifications for better marketability and ease of manufacture adversely affect the degree of improvement
Specifically, the properties and application of magnetic materials strongly affect the antenna radiation pattern, which adversely affects the regenerative properties

Abstract

A double-ridged horn antenna having a higher-order mode suppressor includes a pair of upper and lower ridges arranged opposite to each other, each of the upper and lower ridges having an inner surface to guide electromagnetic waves and an outer surface arranged opposite to the inner surface; upper and lower flares fixedly attached to respective outer surfaces of the upper and lower ridges; left and right flares coupled to the upper and lower flares to form a rectangular cone structure; and metal conductors symmetrically positioned between the upper and lower ridges and the left and right flares.

Description

technical field [0001] Exemplary embodiments of the present invention relate to a dual-ridged horn antenna, and more particularly, to a dual-ridged horn antenna with a higher order mode suppressor configured to improve the antenna's emission and broadband characteristics. Background technique [0002] A double-ridged horn antenna or a double-ridged waveguide is an example of a linearly polarized antenna. Broadband horn antennas using ridges have been proposed as early as the early 20th century and are a wideband antenna pattern that is widely used today. [0003] Figure 1-3 Side, front, and top views of a conventional double-ridge broadband horn antenna, respectively. will refer to Figure 1-3 The operation of the conventional double-ridge broadband horn antenna 100 is described. The upper and lower horn sections 112A and 11B and the left and right horn sections 114A and 114B are configured to transmit the electric field in the horn and maintain the shape of the horn ante...
