SPE-23-8-283-A 

The Taoglas PCS.25.A has been expertly designed as a 2.4GHz antenna for various Bluetooth and Wi-Fi applications. The PCS.25 is an FR4 antenna designed to be mounted via SMD on a PCB. The PCS.25 has been designed to operate both with and without clearance, meaning it can be used on boards where space is at a premium. 

Typical Applications Include: 

- Wearables 

- Keyless Entry 

- Handheld Devices 

- Smart Healthcare 

The PCS.25.A has been designed in a compact form factor of just 15x3x3mm, allowing it to be used in areas where other antennas that are currently on the market are used.. 

Patch antennas can be specifically tuned to customer-specific device environments, subject to NRE and MOQ. Contact your regional Taoglas customer support team to request these services or additional support to integrate and test this antenna’s performance in your device.

## Antenna Integration 

For any given PCB size, the antenna should ideally be placed on the PCB’s corner edge, to take advantage of the ground plane. Optimized matching components can be placed as shown.

## **6.3** PCB Layout | 

The footprint and clearance on the PCB must meet the layout drawing in section (Footprint Drawing). Note the placement of the optimized components. L1 is placed as close as possible to the RF feed (pad 1) within the copper keep out area. L2 is then placed tightly in parallel after that. C1 is an optional component but the footprint is recommended in case it is needed.

## PCB Clearance 

Below shows the antenna footprint and clearance through ALL layers on the PCB. Only the antenna pads and connections to feed and GND are present within this clearance area (marked RED). The clearance area extends to 15.3mm in width and 3.3mm in length from the corner the PCB. This clearance area includes the bottom side and ALL internal layers on the PCB other than the top layer. The clearance area for the top side extends to 12mm in width and 3.3mm in length, 1.8mm in from the edge of the PCB.

## **6.6** Matching Circuit eas 

Matching components with the PCS.25.A are recommended for the antenna to have optimal performance on the evaluation board, located in the spaces specified in the above images. Additional matching components may be necessary for your device, so we recommend incorporating extra component footprints, forming a “pi” network, between the cellular module and the edge of the ground plane.
