Radio navigation antenna system for aircraft |
摘要 |
A radio navigation antenna system suitable for use in an aircraft is disclosed. The fed element of the system is stationary, being at one end of a coaxial conductor which extends through a hollow shaft of a motor. Mounted around the hollow shaft is a ground plane disc capacitively coupled to the outer sleeve of the coaxial conductor, thereby avoiding the use of brushes in the system. A cylindrical dielectric antenna support is mounted on the ground plane disc around the fed element. A T-shaped reflector is formed by a conductive layer on the cylindrical surface of the antenna support.
