Abstract
A travelling wave conductor antenna including a ground plane. The antenna consists of meander-structure conductors made of a conductive material, zigzagging at right angles or at almost right angles. The conductors are placed above an even or deformed ground plane and they alternately comprise portions parallel with the longitudinal axis of the antenna and portions perpendicular or almost perpendicular to said longitudinal axis so that the number of the conductors is even. The conductors are at their ends connected to an antenna feed point by means of electrically equally long or almost equally long conductors.
Claims7
In a travelling wave meander conductor antenna including a ground plane, the improvement comprising:
- meander-structure conductors made of a conductive material, said conductors zigzagging as substantially forming open parallelograms and placed above a ground plane, which conductors alternately comprise first portions parallel with the longitudinal axis of the antenna and second portions substantially perpendicular to said longitudinal axis so that the number of conductors is even, said conductors being connected at their respective ends to an antenna feed point by means of electrically substantially equally long conductors.
