Taoglas MIMO antennas guide security robots

There’s strength in numbers. That’s why antenna systems are increasingly upgrading from single-input/single-output (SISO) architectures to multiple-input/multiple-output (MIMO).

Whether it’s military communications, public safety, smart meters or smartphones, more antenna elements increase channel capacity, reduce transmitting power and increase resistance to multipath fading.

But the smaller the device, the more challenging MIMO becomes from a design perspective, such as providing ample isolation between each antenna element.

That’s key for ensuring that they don’t interfere with one another, which would reduce channel capacity and system performance. For example, the Taoglas Pantheon MA750 is just 85.7 mm tall, with a 145.6 mm diameter, yet its five antennas have 20 dB+ of isolation.

Three additional key features to look for are high radiation efficiency, low envelope correlation and a built-in ground plane, which provides the flexibility to mount the antenna on metal or plastic without affecting performance.

For applications with long cable runs, such as 10 m, low-loss cables are critical for ensuring that a MIMO antenna can establish and maintain a reliable connection. If the antenna is likely to get wet or struck, it is best to use models with IP67 housings made with ultra-durable materials, such as Wonderloy PC-540 PC/ABS alloy.

Enova Robotics makes security robots. “At Enova Robotics, we know reliability is imperative when you are in the business of security and surveillance. That’s why we chose to work with Taoglas and chose their Pantheon MA750 for our PGuard Robot,” said Ahmed Dimassi, production and supply manager, Enova. “This unique antenna delivers powerful MIMO antenna technology, and we knew we could rely on their team to reduce the risks and time associated with integrating it into our technology.”
