## **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 recommended to implement a matching network to optimize the antenna impedance in your application. The EVB is 1 mm thick and has solid ground on the bottom layer (no copper clearance). 

For PCB’s thicker than   mm, it is advised that extra GND is added under the antenna at 1 mm depth in the stack-up. 

Detailed view of antenna pads and copper clearance (footprint is symmetrical and all four pads the same size): 

_Unit: mm_ 

## **Transmission Line** 

The transmission line should be ke t as short as  ossible and be designed to have a characteristic im edance of  0Ω. 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.

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

The evaluation board (Abracon AANI-CH-0072-EVB) is developed to simplify antenna testing and evaluation. It has an arbitrary size of 50 x 20 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. 

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 – 2.4835 GHz range using the components listed below (equivalents may be used): 

X1 = Not mounted X2 = 3.2 pF (Murata GJM1555C1H3R2WB01) X3 = 2.9 pF (Murata GJM1555C1H2R9WB01) 

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. This is further described in the General Implementation Guidelines section below.

## **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. 

- he antenna must be  laced along the PCB edge  i.e.  it cannot be  laced in the middle (see “N/A”). 

- Option 2 or 3 may be the best option for PCB’s much larger than the evaluation board. 

The rectangular copper cutout in the footprint should extend to **at least 0.7 mm depth (with no copper on any layer), followed by a solid ground plane.** ence  for PCB’s thicker than   mm  it is advised that an e tra ground  lane is added at ~1 mm depth from the antenna plane. 

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.
