changing in the ground plane for the fractal antenna has been studied in this research and its effects on the antenna frequency bandwidth for more than frequency bands, results are encouraging, where we get multi band fractal antenna with wide BW for more than 100%.
This paper presents the development and evaluation of BroadBand Electrically Steerable
Parasitic Array Radiator antenna by using eight parasitic radiators BB-ESPAR-8 .
The antenna has a symmetrical structure that consists of: i- one active element as a broad band
shuttle antenna, ii- eight wideband parasitic radiators, iii- cylindrical ground plane, iv- set of
reactances.
