ANT-2.4-CPA Linx Technologies

Datasheet ANT-2.4-CPA 2.4 GHz Directional Embedded Ceramic Patch Antenna The 2.4-CPA compact ceramic patch antenna offers directional signaling at 2.4 GHz with a footprint of only 20 mm x 20 mm on a recommended ground plane size of 40 mm x 40 mm. The 2.4-CPA antenna supports 2.4 GHz ISM applications including Bluetooth and ZigBee , as well as single-band WiFi. The 2.4-CPA antenna mounts to the printed circuit board (PCB) using re-peelable 5000NS adhesive backing which allows for repositioning or reorientation of the antenna. The pin-type connection feeds through the PCB where it is soldered to the feed line. Applications Features 2.4 GHz ISM: Directional radiation pattern orthogonal to antenna surface Bluetooth Compact size, 20 mm x 20 mm x 4 mm ZigBee Peak gain: 5.5 dBi when used with a 40 mm Single-band WiFi/802.11 x 40 mm ground plane. Larger ground planes Sensing and remote monitoring provide increased gain performance Hand-held devices Pin-mount solder connection for direct PCB Internet of Things (IoT) devices attachment Gateways Right-hand circularly polarized (RHCP) Durable re-peelable self-adhesive backing Ordering Information Part Number Description ANT-2.4-CPA 2.4 GHz ceramic patch antenna Available from Linx Technologies and select distributors and representatives.ANT-2.4-CPA Datasheet ANT-2.4-CPA Electrical Specifications Frequency Range 2.4 GHz to 2.5 GHz VSWR (max.) 2.7 2 Return Loss (max.) -6.9 20 .079 Peak Gain (dBi) 5.5 .787 Average Gain (dBi) -0.8 0.60 Efficiency (%) 88 .024 Polarization RHCP Radiation Directional 0.80 Max Power 8 W .031 Wavelength 1/4-wave 20 Electrical Type Radiating patch .787 Impedance 50 2.50 4 Connection Pin type .098 .157 Weight 6.1 g (0.22 oz) Dimensions 20.0 mm x 20.0 mm x 4.0 mm (0.79 in x 0.79 in x 0.16 in) Operating Temperature Range -40 C to +85 C ESD Sensitivity NOT ESD sensitive. As a best practice, Linx may use ESD packaging. Electrical specifications and plots measured with a 40 mm x 40 mm (1.6 in x 1.6 in) ground plane.

The larger the ground plane, the narrower the antenna signal beam, and generally, the better the VSWR performance of the antenna. Relatively smaller ground planes produce wider signal beams. Linx recommends the ground plane size shown in the Electrical Specifications table to achieve performance similar to that shown in this datasheet. 2
