Abstract

This paper describes the characteristics of modified dipole antenna whose arms are bent at their middle points. On the basis of an integral equation method, the authors first analyse a center-fed half-wave dipole, paying special attention to the bending angle of the antenna arm. It is found that the bent dipole with a bending angle of 90 degree can be made to resonate with nearly a pure resistance of 50 OMEGA . Secondly, the authors analyse an asymmetric-fed full-wave bent dipole for the purpose of improving the directivity. Calculations show how a bidirectional beam of increased directivity can be formed as the bending angle of the arm is increased.
