## **Evaluation Board Outline & Matching Circuit** 

The evaluation board (Abracon AANI-CH-0211-EVB) is developed to simplify antenna testing and evaluation. It has a size of 120 mm (L) x 50 mm (W) 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. 

**==> picture [203 x 9] intentionally omitted <==**

**----- Start of picture text -----**<br>
wa<br>**----- End of picture text -----**<br>


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 858 – 878 MHz range using the components listed below (equivalents may be used):

**However, it is common that the resonant frequency will shift during implementation in an arbitrary device. Therefore, this matching may be changed with other values/components/brands for compensation of such effects.

## **Recommended PCB Layout** 

If there are several layers in the PCB, there is an advantage to add vias for smooth interconnection of the ground areas to avoid splits in the ground plane. It is also important that ground clearance is respected through all layers of the PCB. It is recommended to implement a matching network to optimize the antenna impedance in your application.

## **Transmission Line** 

The transmission line should be kept as short as possible and be designed to have a characteristic impedance of 50Ω. Abracon recommends using a Co-Planar Waveguide with Ground (CPWG), which dimensions can be derived by any trusted calculator, using the correct input for PCB materials and layer stack-up.

## **General Implementation Guidelines** 

The antenna can be positioned in different ways, although there are some positions which are more beneficial. The below illustration shows a typical PCB with examples on different antenna positions (the GND cutout is not visualized): 

- The optimal position is usually option 1. Options 2 and 3 are also possible. 

- Th    t     m st b  pl      lo g th   C    g ,     ,  t     ot b  pl        th  m   l   s   “N/A” 

- Option 2 or 3 may be the best option for PCB’s m  h l  g   th   th   v l  t o  bo 

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 below 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.
