Abstract

The condition for axial mode operation in helical antenna according to the classical design data is the helix circumference to wavelength ratio (C/λ) must be in a range of 0.8 to 1.2. In this paper the C/λ ratio is reduced to 0.2 for the wavelength 125 mm. It is achieved by loading the helix in a back cavity. The design concept of helical resonator filter is used for design of this antenna. If the same helix is used with 0.75 λ ground plane it operates in normal mode.
