Optimized patch array antenna for 60 GHz wireless applications

Abstract

The recently developed 60 GHz standard provides a 7 GHz license-free band around 60 GHz for high data-rate wireless communications at the rate of gigabits per second. Due to huge interest in broadband Wireless Personal Area Network (WPAN) applications, a low cost, miniaturized and high performance radio technology at 60 GHz is on high demand. Antenna is a key element and several antennas have been introduced for an increasing number of applications. Patch antennas are among the best candidates for implementing in mmwave band due to their low profile and cost. In this paper, considering system requirements of an indoor wireless link to comply with IEEE 802.15.3c and ECMA 60GHz standards, a 2x2 array of patch antennas has been optimized, fabricated and measured.
