The type of PCB antenna needs to be determined based on the device size and frequency requirements. For example, large-sized boards can use inverted F-type antennas (PIFA), which improve stability through capacitive effects but have slightly lower efficiency; Small size devices are suitable for serpentine or monopole antennas, using the 1/4 wavelength principle to compress space (such as optimizing the length of a 2.4GHz antenna to 23-30mm). High frequency scenarios (such as 5G millimeter waves) require the use of substrates with stable dielectric constants (such as Rogers RO4350B) to reduce losses.
