Re: Which type of antennas is the best one for SRD at 868MHz
Hi,
u have several kind of loopantennas; usually the current distribution along the loop is relative constant, this means that the length of the loop should be small compared with the wavelength, the loop is then tuned to resonance with a capacitor, gain of such a antenna in practise is rather low , from -25 dbi to 10 dbi...but they are small
if u have more place u can consider to use a full wavelength loopantenna, this has a very good performance, gains of 2 dbi are feasible
maybe this is of some help to u,
Tony
