Abstract:

The characteristics of a balun-fed, open-sleeve dipole mounted in front of a metallic reflector for operation in the 225 to 400 MHz band are investigated. A parametric study is made of the VSWR response as a function of dipole and sleeve diameter, sleeve length, and sleeve-to-dipole spacing. It is shown that an open-sleeve dipole can be operated over a bandwidth of 1.81 as compared with an operating bandwidth of approximately 1.251 for a conventional cylindrical dipole with the same diameter. Pattern and gain data are presented for an open-sleeve dipole mounted in front of a flat metallic reflector and in front of a right circular cylinder. Preliminary results of mutual impedance effects are also discussed. Author
