Antenna Design
The design and positioning of the antenna is as crucial as the module performance itself in
achieving a good wireless system range. The following will assist the designer in maximizing
system performance.
The antenna should be kept as far away from sources of electrical interference as physically possible.
If necessary, additional power line decoupling capacitors should be placed close to the module.
The antenna ‘hot end’ should be kept clear of any objects, especially any metal as this can severely re-
strict the efficiency of the antenna to receive power. Any earth planes restricting the radiation path to
the antenna will also have the same effect.
Best range is achieved with either a straight piece of wire, rod or PCB track @ ¼ wavelength (8cm
@ 916.5MHz). Further range may be achieved if the ¼ wave antenna is placed perpendicular in the
middle of a solid earth plane measuring at least 16cm radius. In this case, the antenna should be
connected to the module via some 50 ohm characteristic impedance coax.
