Title: 47 GHz Dual-Mode Feedhorn with Internal Transition to WR22 Rectangular Waveguide.
Authors: Pawlan, Jeffrey1, Rengarajan, Sembiam1
Source: Microwave Journal. Mar2026, Vol. 69 Issue 3, p70-78. 6p.
Subjects: Rectangular waveguides, Modular construction, Beam steering
Abstract: The article focuses on the development of a high-quality 47 GHz feedhorn designed for commercial and amateur radio use, offering minimal return loss and precise beam control. Topics include adaptations of the historic Pickett-Potter horn design, tight machining and modular fabrication for high accuracy, and a novel internal transition from circular to WR22 rectangular waveguide.
