Shortened aperture dipole antenna
Abstract:
A center fed dipole with a shortened aperture is described. A first rod-like radiator element approximately a quarter wavelength long at the center operating frequency of the antenna is coupled to the inner conductor of a coaxial transmission line. A second radiator element includes a hollow-conductive cylinder, coaxial with the coaxial transmission line, and a coil. The conductive cylinder is substantially less than a quarter wavelength long at the center operating frequency of the antenna. The conductive cylinder is coupled at one end to the outer conductor of the coaxial transmission line and the end of the cylinder remote from the one end is coupled to the coil.
