Antennas work on metal surfaces without de-tuning

A family of antennas from Antenova has been engineered to operate without de-tuning on metal surfaces or where the product housing is mainly metal. According to the company, these situations normally make it difficult for an antenna to operate.

Called the Zenon range, the 2.4GHz devices are formed of two layers, each isolated from the other electrically, so as to provide RF shielding. This, the company notes, means the antenna can be placed on any kind of material and it will radiate effectively in the direction pointing away from the base material.

Zenon SR4W030 is a low profile device for Bluetooth, Wi-Fi, ZigBee and ISM applications. Measuring only 23 x 16 x 1.6mm, the antenna is made from rigid FR4 laminate and comes with a choice of 100mm or 150mm of 1.13mm cable and an IPEX MHF connector.

“There are very few antennas that are as thin as Zenon and can be mounted on a metal surface,” said Colin Newman, CEO at Antenova. “This antenna is ideal for devices like lighting chassis in metal cases, or bicycles with metal frames. It could also be used for smart lighting, portable devices, set-top boxes, smart meters and other network devices.”
