However, the user may like to elaborate with the tuning if the implementation causes a resonant frequency shift. This part shows two examples of how a simple frequency tuning can be implemented.

Below picture shows a typical PCB with six possible antenna positions. The positions have been arranged according to the best general fit. = feed section (pin 1 & pin 2) The antenna should be aligned with the PCB edge if possible. It is also important to align pin 1 & 2 along the outer side of the PCB, and even more preferably close to a corner. This fact makes position 2, 3 and 6 difficult to define, why these positions are less optimal. The OnBoard SMD 2400 antenna enables that small electrical components are mounted inside the antenna keep-out block. This may have an impact on the antenna tuning and radiated performance but is fully possible if there is limited space on the PCB. Another general aspect on surface mounted antennas is regarding the PCB population. If other electrical components are positioned in the surrounding area of the antenna, some impact on the antenna tuning and radiated performance may be expected. It is recommended that such components are distributed below a topographical slope that starts on PCB level at the antenna keep-out block, and slowly increases the height. It shall also be highlighted that plastic and metal parts in the near proximity of antennas may influence the antenna tuning and/or performance. This aspect should be noted as a general guideline for all antennas. The effects are difficult to estimate without detailed information, but it is common that a plastic housing above the antenna shifts the resonant frequency down. It is recommended to measure the antenna in the actual device after implementation.
