## **Antenna Footprint** 

The dimensions of the copper cutout and solder pad positions are shown in the image below. The antenna and the footprint are symmetrical. This means that the antenna can be fed from either side (from the right in the example). 

For a detailed antenna footprint example: https://abracon.com/Support/Footprint/AANI-NI-0013-EVB-Footprint.zip 

## **Antenna Pin Numbering** 

The antenna should be mounted on a ground (GND) plane, keeping the correct clearance area(s). 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 there is ground clearance around the non-connected (NC) pads, through all layers of the PCB. Thanks to symmetry, the antenna can be fed on either pad 3 or 4. Pads 6 and 7 are connected via top load capacitors. Thermal relief connections can be utilized on the GND pads. 

|**Pin**|**Feeding from the Right**|**Feeding from the Left**|
|---|---|---|
|1|NC|NC|
|2|NC|NC|

|4|**NC**|**RF-feed**|
|5|GND|GND|

The evaluation board (Abracon P/N: AANI-NI-0013-EVB) is developed to showcase the performance of the Niche stamped metal antenna on a typical PCB and to simplify antenna testing and evaluation. It has a size of 50 x 20 mm and includes an SMA connector. The performance will vary with different PCB sizes. Abracon can offer support to optimize the antenna for specific applications. 

**==> picture [79 x 36] intentionally omitted <==**

**----- Start of picture text -----**<br>
Matching<br>Network<br>**----- End of picture text -----**<br>


The evaluation board has a matching circuit implemented next to the antenna to enable optimization possibilities for the user. The C1 and C4-C6 component footprints are sized for 0402 (1005 metric) SMD components. The C2 and C3 component footprints are sized for 0201 (0603 metric) SMD components. 

The standard tuning for the evaluation board is the following (can be replaced by equivalent): 

C1 = 0.4 pF (GJM1555C1HR40WB01) C4 = Not mounted C2 = 0.7 pF (GJM0335C1HR70WB01) C5 = Zero Ohm (KOA Speer RK73Z1ETTP) C3 = 0.8 pF (GJM0335C1HR80WB01) C6 = Not mounted 

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.

The left picture shows a typical PCB with examples on different antenna positions. The optimal position is option 1. Options 2 and 3 are also possible. The antenna must be placed along the PCB edge, i.e., it cannot be placed in the middle. Option 2 or 3 may be the best option for larger PCBs (>> 50 x 20 mm). 

**8.00 x 4.85 x 0.54 mm RoHS/RoHS II Compliant MSL Level = 1** 

Antenna Positions: 

Antenna cutout & via-structure: 

The rectangular copper cutout in the footprint needs to go through all the layers in the PCB stackup, meaning that there cannot be copper on any layer in this area. It is also recommended to have a good via-structure around the cutout and the edge of the ground plane, see the right image above. 

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 and to implement a matching network on the antenna feed to adjust for the potential frequency shift. 

The Stamped Metal Niche antenna shows great performance when potted compared to other antenna solutions and has also shown good performance in proximity of metal and other harsh antenna environments. 

## **Part Marking** 

The top marking of the antenna is arranged according to the following illustration: 

“YYWW” is the date code: YY = Year WW = Week “0013” is the product ID (AANI-NI-0013)
