Product Brief ANT-915-CPA 915 MHz Directional Embedded Ceramic Patch Antenna The 915-CPA compact ceramic patch antenna offers directional signaling at 915 MHz with a footprint of only 25 mm x 25 mm on a recommended ground plane size of 40 mm x 40 mm. The 915-CPA antenna is ideal for RFID and hand- held applications and other 915 MHz ISM band applications where directional signaling is desired. The 915-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. Features Applications Directional radiation pattern orthogonal to Smart Home networking antenna surface Security systems Compact size, 25 mm x 25 mm x 4 mm Home weather stations Peak gain: 1.5 dBi when used with a 40 mm Remote sensing, monitoring and control x 40 mm ground plane. Larger ground planes Security systems provide increased gain performance Industrial machinery Pin-mount solder connection for direct PCB attachment Keyless entry systems Right-hand circularly polarized (RHCP) UHF RFID devices Durable re-peelable self-adhesive backing Hand-held devices Low-power, wide-area (LPWA) applications LoRaWAN Sigfox Ordering Information Part Number Description ANT-915-CPA 915 MHz ceramic patch antenna Available from Linx Technologies and select distributors and representatives.ANT-915-CPA Product Brief Electrical Specifications Frequency Range 915 MHz VSWR (max.) 1.2 Return Loss (max.) -21.1 Peak Gain (dBi) 1.5 Average Gain (dBi) -9.7 Efficiency (%) 23 Polarization RHCP Radiation Directional Max Power 8 W Wavelength 1/4-wave Electrical Type Radiating patch Impedance 50 Connection Pin type Weight 13.2 g (0.46 oz) Dimensions 25.0 mm x 25.0 mm x 4.0 mm (1.00 in x 1.00 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 VSWR Figure 1 provides the voltage standing wave ratio (VSWR) across the antenna bandwidth. VSWR describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of the percentage of transmitter power reflected back from the antenna. 10 60 9 8 50 7 40 6 30 5 4 20 3 10 2 1 0 900 905 910 915 920 925 930 Frequency (MHz) Figure 1.
