ABSTRACT:
The antenna represents colinearly arranged half-wave dipoles. On the side of each final half-wave dipole is a quarter-wave dipole. The connection between the dipoles is alternately capacitive and inductive each providing a phase shift within the range of from 60 to 120 electrical degrees. The terminal of the antenna is asymmetrically deduced from the free end of one of the final half-wave dipoles and the adjacent end of the nearby quarter-wave dipole. This antenna can be used in reception and transmission of electromagnetic energy and shows a considerably increased gain.
