4.5 Antenna Design Requirements
4.5.1 Antenna Design Indicators
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 line from the antenna port of MU709 to the antenna is also part of the
antenna. The line loss increases with the line length and the frequency. It is
recommended that the line loss is as low as possible.
