Smart mobile wireless LAN card antenna

The design and development of a smart antenna for a wireless local area network (WLAN) card for portable and mobile terminals are proposed. The antenna uses an eight PIFA element cylindrical array wrapped around a 2 cm high and 5 cm diameter conducting cylinder placed on a LAN card. The antenna beam is switched by a 1-to-8 way 2-element radial switch, which can generate eight individual equispaced beams suitable for portable and mobile applications.
