Abstract
A cylindrical Fresnel zone antenna as a candidate for a base station i
n wireless indoor LAN systems is described. An arbitrary angle-tilted
fan beam in azimuth can be achieved by moving the position of the stri
p dipole feed at the cylinder center. A simple theory based on the dif
fraction integral is developed which predicts the antenna radiation ch
aracteristics. The antenna fabrication and measurement are carried out
at 9 GHz with good agreement between calculated and measured results.
