Dual-band Wi-Fi antenna carries video streaming in small connected devices

June 26, 2015 // By Graham Prophet
Antenova, manufacturer of antennas and RF antenna modules for M2M and connected devices, has added a small dual-band antenna for the Wi-Fi 802.11n and ac 2.4 – 2.5 GHz and 4.9 – 5.9 GHz bands.

The antenna, called Mutica, is designed to fit within a reduced ground plane on the host PCB, for use in smaller Wi-Fi products and wireless accessories. The picture above shows the antennna evaluation board. Mutica is an SMD mounted antenna for all dual-band Wi-Fi applications, especially those requiring high speed data transfer and multiple-in multiple-out (MIMO) applications, for example security cameras, video cameras, set-top-boxes and devices for connected vehicles. Its specifications will also suit Wi-Fi access points, portable electronics, headsets, PC cards, games consoles, network devices and wearable electronics.

According to Antenova, “Over half of the [Wi-Fi enabled] products shipped are dual band 2.4GHz /5GHz, and the market is forecast to grow further over the next five years making 802.11ac the prevailing WLAN standard. 5Ghz 802.11ac offers High Definition video streaming with more channels and less interference than at 2.4GHz. This coupled with the high efficiency of the Mutica antenna will help to support faster data rates, fewer disconnects and better battery life in portable devices”.

Antenova’s approach to the design of its antennas, which it calls “Design For Integration” (DFI), makes use of the fact that the antennas are always embedded within a customer’s product; Antenova designs them so that the RF elements can easily be added to the customer’s design, and so that the antenna will provide excellent performance when it is placed in position on the PCB. This is backed by CAD footprint files for each antenna.

The Mutica antenna is the first in the new family of lamiiANT FR4 SMD antennas which Antenova announced earlier in 2015.
