Low-profile 2.4GHz antennas work on metal surfaces
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.
Zenon, part number SR4W030, is aimed at Bluetooth, Wi-Fi, ZigBee and ISM applications and boasts a very low profile, measuring only 23x16x1.6mm. 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 – and comes with O-ring cable spacers for when the antenna is mounted directly on metal.
Zenon can be 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.
