Abstract
- This paper describes the design of a slit on ground plane to improve the axial ratio of the spiral antenna for the NLJD system application. A proposed slit shape located on the ground plane is changed to compare with the archimedean spiral slit shape of the antenna in reference [7]. In order to improve the axial ratio, the slit on the ground plane is divided by the uniform angle and the conductor of position where the current has the opposite direction each other is eliminated. Measured return loss, radiation pattern and gain show a good agreement with the computer simulation results. Even though the proposed slit structure on the ground plane was changed to compare with ones of reference [7], the characteristics such as return loss, radiation pattern and gain are not almost changed and only the axial ratio was remarkably improved at 4.88 GHz.
