This antenna has a gain peak of dBi and a bandwidth of 2 GHz from GHz to GHz. The angle coverage of 240 in the azimuth plane with gain 2 dBi higher. The total dimension of the antenna array is cm3 which is fabricated on RO4003C substrate. The antenna has been fabricated and measured the measurement and the simulation results are in good agreement. Keywords Planar array Printed dipole-Yagi antenna Fan beam Series feed. 1. INTRODUCTION Nowadays Wi-Fi technology is operated based on IEEE 802n ac standard at 5 GHz Wireless local area networks WLANs Personal area network PAN and Dedicated short range communication DSRC- 1 2 . Outdoor access points request integrated antenna installed on the wall or public area for serving activities in urban area 3 4 . Thus it is a desirable to design a compact low cost high gain and broadband antenna. In order to transmit broadcast signal omnidirectional antenna system is necessary. However the gain of omnidirectional antenna is only 2 dBi it limits the coverage area of access points. There are several methods to improve the coverage area of outdoor access points such as high gain and broadband omnidirectional antenna 5-8 MIMO array 9 and smart antenna 10 11 . For all above presented papers high gain and wide-angle radiation antennas are attractive solutions for Wi-Fi outdoor access points. In this paper we propose a compact high gain broadband and wide .
