Chapter 2: Antenna Matching

Chapter 2

Antenna Matching

The most important thing one must always remember when designing a matching circuit for antenna is that only inductors or capacitors can be used. In active microwave circuit designs, such as amplifier designs, resistors are frequently used to improve the port matching and circuit stability [1]. But in antenna designs, one should NEVER use resistors or other lossy components. The whole purpose of an antenna in a cellular device is to transmit or receive power, so the efficiency of the antenna is the most critical parameter. Whenever a resistor is added to a matching circuit, the efficiency always drops and that is not our goal. This mistake is repeatedly made by amateur antenna designers, so it is better to set the record straight before we....
