Antennas have become an essential part of consumer electronics, and without realizing, we carry multiple antennas on our person every day. When discussing antennas, the term “impedance matching” commonly appears during the design and final application phases. What is so important about impedance matching? The antenna must be impedance matched when assembled for the end-user environment so that it operates in the desired frequency band with maximum efficiency. Optimal efficiency results in maximum range, minimum power consumption, reduced heating and reliable data throughput. It is essential to realize that an antenna itself can be considered an impedance transformer.
