This also means that no ground cutout area is required under the antenna. If there are several layers in the PCB, there is an advantage to add via holes for interconnection of the ground areas. It is also very important that there is a ground clearance around the NC pads and the RF feed pad, through all layers of the PCB. Otherwise, there will be capacitive coupling which may detune the antenna. Pin configuration PCB Layout (from evaluation board) The antenna is preferably positioned along one side of the PCB ground plane, where pin 1 shall be as close as possible to the layout corner. It is also recommended to implement a pi-matching network as seen in the PCB layout to compensate for eventual mismatch due to the practical implementation. The components can be positioned below the antenna next to the feed pad. See “Evaluation Board Outline & Matching Circuit” section for more details.

It has an arbitrary size of 100 x 50 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. C1 Transmission line C3 Antenna feed C3 C2 C1 C2 Matching circuit The antenna needs a matching circuit to adjust the resonant frequency balance. When delivered, the evaluation board is tuned for optimum balance at the 2.4 GHz band. The component values for this setup is C1 = 1.5nH, C2 = 0.5pF, C3 = N/A. However, it is common that the resonant frequency will shift during implementation in an arbitrary device. Therefore, this matching may be changed for compensation of such effects. 5101 Hidden Creek Ln Spicewood TX 78669 Phone: 512-371-6159 | Fax: 512-351-8858 For terms and conditions of sales, please visit: www.abracon.com REVISED: 07-19-21 ABRACON IS ISO9001-2015 CERTIFIED 2.4 GHz - Wi-Fi/BT/BLE Stamped Metal Antenna PRO-OB-440 Request Samples Check Inventory 13.75 x 5.23 x 3.53 mm RoHS/RoHS II Compliant MSL Level = 1 Reflection Characteristics - Return Loss Total Radiation Efficiency Maximum Radiation Gain 5101 Hidden Creek Ln Spicewood TX 78669 Phone: 512-371-6159 | Fax: 512-351-8858 For terms and conditions of sales, please visit: www.abracon.com REVISED: 07-19-21 ABRACON IS ISO9001-2015 CERTIFIED 2.4 GHz - Wi-Fi/BT/BLE Stamped Metal Antenna PRO-OB-440 Request Samples Check Inventory Radiation Characteristics - 2D Pattern (2400 MHz) 5101 Hidden Creek Ln Spicewood TX 78669 Phone: 512-371-6159 | Fax: 512-351-8858 For terms and conditions of sales, please visit: www.abracon.com 13.75 x 5.23 x 3.53 mm RoHS/RoHS II Compliant MSL Level = 1 REVISED: 07-19-21 ABRACON IS ISO9001-2015 CERTIFIED 2.4 GHz - Wi-Fi/BT/BLE Stamped Metal Antenna PRO-OB-440 Request Samples Check Inventory Radiation Characteristics - 2D Pattern (2500 MHz) 5101 Hidden Creek Ln Spicewood TX 78669 Phone: 512-371-6159 | Fax: 512-351-8858 For terms and conditions of sales, please visit: www.abracon.com 13.75 x 5.23 x 3.53 mm RoHS/RoHS II Compliant MSL Level = 1 REVISED: 07-19-21 ABRACON IS ISO9001-2015 CERTIFIED 2.4 GHz - Wi-Fi/BT/BLE Stamped Metal Antenna PRO-OB-440 Request Samples Check Inventory Antenna Tuning & Impedance Matching 13.75 x 5.23 x 3.53 mm RoHS/RoHS II Compliant MSL Level = 1 The antenna should have nominal tuning in most applications when C1 = 0 Ohm (measured with coaxial cable on the evaluation board). 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. Optimal 4&1 5 6 3 2 = 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. 5101 Hidden Creek Ln Spicewood TX 78669 Phone: 512-371-6159 | Fax: 512-351-8858 For terms and conditions of sales, please visit: www.abracon.com REVISED: 07-19-21 ABRACON IS ISO9001-2015 CERTIFIED 2.4 GHz - Wi-Fi/BT/BLE Stamped Metal Antenna PRO-OB-440 Request Samples Check Inventory Park Marking 13.75 x 5.23 x 3.53 mm RoHS/RoHS II Compliant MSL Level = 1 The top marking of the antenna is arranged according to the following illustration.
