It has an arbitrary size of 51 x 18 mm and includes an SMA connector. The purpose is to give a reference design for an optimal antenna implementation. The evaluation board can also be used to test other implementations by cutting and soldering the PCB into any device. Evaluation board outline The evaluation board has a matching circuit implemented next to the antenna. This is aimed to enable optimization possibilities for the user. The component positions are sized for 0402 (1005 metric) SMD components. The antenna requires a matching circuit to fine -tune the resonant frequency and achieve optimal balance. The evaluation board is pre -tuned for optimal performance in the 2.4 –2.5 GHz range using the components listed below (equivalents may be used): X1 = 7.3 nH (Murata LQW15AN7N3G00D) X2 = 0.8 pF (Murata GJM1555C1HR80WB01D) X3 = not mounted However, it is common that the resonant frequency will shift during im plementation in an arbitrary device. Therefore, this matching may be changed with other values/components/brands for compensation of such effects. This is further described in the General Implementation Guidelines section below.

The below illustration shows a typical PCB with examples on different antenna positions ; where option 1 typically yields slightly better performance, and option 2 uses less space of the PCB. The rectangular copper cutout in the footprint must extend through all layers of the PCB stack-up, ensuring there is no copper on any layer in this area . Additionally, a robust via structure around the cutout and along the edge of the ground plane is highly recommended for optimal performance. It is important to note that plastic and metal parts in close proximity to antennas may significantly affect antenna tuning and performance. For instance, a plastic housing above the antenna often causes the resonant frequency to shift downward. Since such effects are challenging to predict without detailed design information, it is recommended to measure the antenna performance in the final device after implementation. To compensate for potential frequency shifts, implementing a matching network on the antenna feed is advisable. Another general consideration for surface-mounted antennas relates to PCB population. Electrical components placed near the antenna may impact its tuning and radiation performance. To mitigate this, components in the surrounding area should be positioned b elow a topographical slope. This slope should begin at the PCB level near the antenna's designated keep-out zone and gradually increase in height as distance from the antenna grows.
