Antenova has announced two new antennas for the 802.11a/b/g/n/ac wireless standard. These new antennas are designed for the profusion of high bandwidth applications emerging in the consumer entertainment sector – specifically set-top boxes, IPTV and content streaming devices - all of which are seeing strong growth, in parallel with the roll-out of fibre to the home and the increase of IPTV services.
As content streaming and video-on-demand push consumer based Wi-Fi networks to their limits, manufacturers are moving up to the 5 GHz band, which offers the benefits of a less crowded spectrum, with low interference, fewer disconnects and signals as fast as 1Gbps.
The two new SMD antennas introduced by Antenova have been developed for this market - specifically for smart TVs, wearable electronics, access points, portable devices, PC cards, internet-connected set-top boxes, network devices and consumer MIMO applications.
The first antenna, Sharpi, (part no. SRC5G027) is an ultra-compact ceramic antenna solution for 5 GHz, measuring just 1 mm x 0.5 mm x 0.5 mm. The second antenna, Trogona (part no. SR42W009) is manufactured from FR4 materials, and is a dual-band antenna operating in both Wi-Fi bands, 2.4 to 2.5 GHz and 5.17 to 5.84 GHz. Trogona works over a ground plane with no clearance, and is also ideal for gaming consoles and IP cameras.
Both antennas are designed for integration and maintain good performance when placed within a device. They are easy to integrate into a PCB layout using their guidance on positioning, and Antenova also offers matching and testing services if and when they are required.
Antenova feels the 5 GHz spectrum will give consumers a better user experience, with more bandwidth, more robust wireless signals, better reach and less interference from other devices using 2.4 GHz. An increasing number of manufacturers are starting to have requirements for compact antennas in these frequency bands. The Sharpi and Trogona have been developed in response to their customers requests for small SMD antennas that meet the 802.11/ac standard.
