Abstract

A Yagi-type antenna is presented for the shaped radiation pattern synthesis, which will become very useful in the applications of wireless communications. The shaped pattern is formed by properly allocating the directors to weight the directivities in a various directions since the uses of directors have been shown to increase the directivity of a Yagi antenna radiation. Both numerical and experimental examinations have validated the current approach to be very effective in both applications and cost.
