N2 - This paper describes the characteristics of modified dipole antennae whose arms are bent at their middle points. On the basis of an integral equation method, we first analyse a centre-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° can be made to resonate with nearly a pure resistance of 50 Ω. Secondly, we 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.
