Ultra-small 2.4-GHz antenna

Wireless products continue to add more and more separate wireless standards and links, and an increasing number of functions, into smaller and smaller spaces. Getting an efficient antenna in the minimum printed-board area is a constant challenge. Antenova designed its Fusca 2.4-GHz antenna— the smallest in the gigaNOVA range— with ease of integration into wireless devices in mind and intends it to work with embedded short-range wireless applications such as Bluetooth, Wi-Fi, Wibree and ZigBee. WiBree recently merged with the Bluetooth SIG and will henceforth be called Bluetooth ULP for ultra-low-power; its proponents expect further growth in wireless personal-areanetwork-product designs.

Fusca A10192-L occupies 4
3
1.1 mm —much smaller than the SMA connector on the company’s test board— for use in wireless headsets, personal navigation devices, portable media players and mobile phones. Antenova designed it for SMD mounting with standard production equipment; the antenna requiresonly a minimal ground plane to operate.
