Product Brief ANT-GNSSCP-SM12L1 Surface-Mount Ceramic Patch GNSS Antenna The GNSSCP-SM12L1 is a 12 mm x 12 mm square surface-mount ceramic patch antenna for embedded GPS/GLONASS/GALILEO/BeiDou global navigation satellite system (GNSS) operation. It provides gain and radiation pattern performance supporting solutions with high location accuracy, rapid satellite signal reception and lock, and quick time to first fix. The GNSSCP-SM12L1 offers an extended temperature range to +105 C for compliance to automotive standard AEC-Q200 Grade 2. The GNSSCP-SM12L1 is available in tape and reel packaging and is designed for reflow-solder mounting directly to a printed circuit board for high- volume applications. Features Applications Performance at 1567.24 MHz to 1583.6 MHz Global navigation GNSS VSWR: 7.0 GPS L1 Peak Gain: 2.9 dBi Galileo E1 Efficiency: 53% GLONASS II L1 Directional radiation pattern orthogonal to Beidou B1-BOC antenna surface QZSS L1 Right-hand circularly polarized (RHCP) Timing solutions Extended operation to +105 C Automotive location AEC-Q200 Grade 2 compliance Omnidirectional radiation pattern Direct surface-mount PCB attachment Reflow- or hand-solder assembly Ordering Information Part Number Description ANT-GNSSCP-SM12L1 GNSS ceramic patch antenna with surface-mount solder connection Available from Linx Technologies and select distributors and representatives.ANT-GNSSCP-SM12L1 Product Brief Electrical Specifications GPS L1, GALILEO E1, GLONASS II GNSSCP-SM12L1 GLONASS II L1 L1, Beidou B1-BOC, QZSS L1 Center Frequency 1575.42 MHz 1602 MHz Frequency Range 1567.24 MHz to 1583.60 MHz 1593.31 MHz to 1608.68 MHz VSWR (max) 7.0 6.1 Peak Gain (dBi) 2.9 1.0 10 Deg.

Electrical specifications and plots measured with a 50 mm x 50 mm (1.97 in x 1.97 in) reference 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. 8 60 7 50 6 40 5 30 4 20 3 10 2 1 0 1550 1560 1570 1580 1590 1600 1610 Frequency (MHz) Figure 1.
