DESCRIPTION EQUIPMENT REQUIREMENT Frequency Range VNA E5071C 2.4~2.5GHz Return Loss VNA E5071C < -6 dB Peak Gain (Max) OTA Chamber 3.7dBi Average Total Efficiency OTA Chamber >70% Polarization OTA Chamber Linear Input Impedance VNA E5071C 50 Ohms Note that the above antenna performance is measured with just the antenna mounted on a recommended PCB to similar a free-space condition. When implement into the system, the frequency resonant might be off-tune due to the loading of surrounding components especially metal plane. This off-tune can be compensated through matching. Although module manufacturers specify a peak gain limit, it is based on free-space conditions. The peak gain will be degraded by 1 to 2dBi in the actual implementation as the radiation pattern will change due to the surround components. As such, during selection of antenna, you can select one with high peak gain to compensate for the loss. Molex can offer assistant to choose the best location and best tuning in-order to meet this peak gain requirement.
