Properly matching an antenna to a transceiver is one of the easiest ways to extend the signal range and battery life of a smartphone, laptop, or any other wireless device. According to the inverse square law of radio waves, only a 6-dB improvement in path loss from improved matching results in a device that transmits and receives at twice the range. A spectrum analyzer with a tracking generator can check an antenna match by looking at the voltage standing wave ratio (VSWR). But the best tool
