Non-detuning 2.4 GHz antenna
Antennas are back magic to many electronicists and to hear that antennas may detune in the presence of metal is a further argument to leave all that “RF wizardry” to the specialists. And you can, safely. Antenova, winner of an Elektra 2017 award, can now supply a 2.4-GHz antenna which is designed to operate without de-tuning on metal surfaces or where the product housing is mainly metal. The antennas from the ‘Reflector’ range consist of two layers, one electrically isolated from the other, so as to provide RF shielding to the second layer. As a result the antenna can be placed on any kind of material and it will radiate effectively in the direction pointing away from the base material.
