Miniature 2.4GHz Antenna Works On Metal Surfaces


Antenova has launched a new 2.4GHz low-profile antennas for metal surfaces. Called Zenon, 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.

This antenna is designed to operate without de-tuning on metal surfaces or where the product housing is mainly metal, a situation where it is normally extremely difficult for an antenna to operate.

Zenon, part number SR4W030, is a high performance 2.4GHz antenna for Bluetooth, Wi-Fi, ZigBee and ISM.

The REFLECTOR antennas are formed of two layers, one electrically isolated from the other, so as to provide RF shielding to the second layer. This means that the antenna can be placed on any kind of material and it will radiate effectively in the direction pointing away from the base material.


The antenna has an exceptionally low profile, measuring only 23mm x 16mm x 1.6mm. It is manufactured from rigid FR4 laminate and has a 1.13mm cable and IPEX MHF connector. The cable can be specified in two standard lengths, 100mm or 150mm.

In addition, Zenon allows quick and easy integration into a customer’s design. It is simply fixed in position with a peel-back self-adhesive strip, and can either be inserted into a new design or it can be retro-fitted into an existing design. No tuning or matching is required, the company contends.
