Antenna Efficiency
Antenna efficiency is the ratio of the input power to the radiated or received power of
an antenna. The radiated power of an antenna is always lower than the input power
due to the following antenna losses: return loss, material loss, and coupling loss. The
efficiency of an antenna relates to its electrical dimensions. To be specific, the
antenna efficiency increases with the electrical dimensions. In addition, the
transmission cable from the antenna port of MU739 to the antenna is also part of the
antenna. The cable loss increases with the cable length and the frequency. It is
recommended that the cable loss be as low as possible, for example, U.FL-LP-088
made by HRS.
The following antenna efficiency (free space) is recommended for MU739 to ensure
high radio performance of the module: Efficiency of the master antenna > 40% (–4
dB), In addition, the efficiency should be tested with the transmission cable.
