Abstract :
This paper presents an additional work on a previous EBG cylindrical antenna in order to conceive a steerable antenna for Radar applications which require the coverage of the horizontal plane with a high gain (higher than 25 dB). The already designed antenna provides 18 beams with 15 dBi of maximum directivity. That is why some modifications were applied on it in order to obtain more beams in the horizontal plane (30 beams) and increase its gain. Moreover, the theories of cylindrical arrays in the horizontal plane and the multi-feed in the vertical plane are used which allows further gain improvement and reaching the required one.
