Description
The PRO-EB-450 Evaluation board is designed to provide a means to facilitate engineering evaluation of the OnBoard 2.4 GHz SMD antenna: PRO-OB-440. With a typical operating frequency range of 2.4 ~ 2.5 GHz, the antenna can be used for WiFi/BT/BLE/ZigBee/ISM applications. To evaluate the performance of antenna, calibrate the Vector Network analyzer (VNA) for the testing frequency band and connect the evaluation board to the calibrated port using the given SMA connector on the board.

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 a ground clearance around the NC pads and the RF feed pad, through all layers of the PCB. It is recommended to implement a matching network to optimize the antenna impedance in your application. The components can be positioned under the antenna. See recommendations in the figures below.

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. 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 frequency band. The component values for this setup are: C1 = 1.5 nH C2 = 0.5 pF 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. This is further described in General Implementation Guidelines section below. Note: Overall Evaluation Board dimensions: 100 x 50 mm. Transmission line Antenna feed C2 C1

Below picture shows a typical PCB with examples on different antenna positions. The optimal position is option 1 or 4. = GND pin(s) The antenna should be aligned with the PCB edge if possible, preferably with the GND pin(s) close to a corner. The antenna enables that small electrical components are mounted inside the antenna keep-out block. This is a space- efficient solution which has very little influence on the performance. It may have an impact on the antenna tuning, 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. Optimal 1 & 4 2 & 5
