A microstrip Yagi antenna design with array application
has been presented for coverage standard IEEE 802.11 in 5
GHz band for Wi-Fi frequency range of 5.15-5.875 GHz. The
simulation tool CST is utilized to perform the antenna design
and optimization process. The antenna consists of driven patch
element and a few parasitically coupled director and reflector
patch elements. The effect of each element to the antenna
performance has been studied in achieving high gain with good
return loss.
