TL;DR: In this paper, the authors proposed a compact design of an ultra wideband dual ridged horn antenna (DRHA) which operates from 3.1 GHz to 17.55 GHz with peak gain of about 14.26 dBi.
Abstract: Compact design of an ultra wideband dual ridged horn antenna (DRHA) is proposed in this paper. The antenna operates from 3.1 GHz to 17.55 GHz with peak gain of about 14.26 dBi. Derived closed form expression for the ridged tapering is also proposed. Simulations results are obtained using commercial EM simulator and fabricated prototype is designed and measured for validation.

TL;DR: In this paper, the authors proposed an ultra wideband (UWB) double-ridge horn antenna, whose operating frequency is 6GHz-67GHz, and measured results of VSWR are less than 2.5, the gain are 13dB Typ.
Abstract: To reduce the difficulty and cost of measurement, this paper proposes an ultra-wideband (UWB) double-ridge horn antenna, whose operating frequency is 6GHz-67GHz. The measured results of VSWR are less than 2.5, the gain are 13dB Typ. and the cross polarization isolation are 30dB Typ. This horn antenna has been widely used in measured fields and appears good performance.

TL;DR: In this paper, the cutoff frequency and impedance of a rectangular wave guide with a rectangular ridge projecting inward from one or both sides are presented. But the cutoff is strictly accurate only for an extremely thin cross section.
Abstract: Equations and curves giving cutoff frequency and impedance are presented for rectangular wave guide having a rectangular ridge projecting inward from one or both sides. It is shown that ridge wave guide has a lower cutoff frequency and impedance and greater higher-mode separation than a plain rectangular wave guide of the same width and height. The cutoff frequency equation is fairly accurate for any practical cross section. The impedance equation is strictly accurate only for an extremely thin cross section. Values found by the use of this equation have, however, been found to check experimental values very closely. A number of uses for this type of wave guide are suggested.
