Product Brief ANT-GNSSCP-TH18L1 Ceramic Patch GNSS Antenna The GNSSCP-TH18L1 is an 18 mm x 18 mm square ceramic patch antenna for GPS/GLONASS/ GALILEO/BeiDou global navigation satellite system (GNSS) operation. It provides excellent 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-TH18L1 offers an extended temperature range to +105 C for compliance to automotive standard AEC-Q200 Grade 2. The antenna is mounted via attached adhesive patch and has a solder pin signal connection. Features Applications Performance at 1567.24 MHz to 1583.60 MHz Global navigation GNSS VSWR: 2.8 GPS L1 Peak Gain: 5.1 dBi Galileo E1 Efficiency: 66% GLONASS I L1 Directional radiation pattern orthogonal to GLONASS II L1 antenna surface Beidou B1-BOC Right-hand circularly polarized (RHCP) Beidou B1-2 Extended operation to +105 C QZSS L1 AEC-Q200 Grade 2 compliance Timing solutions Adhesive mounting to PCB Automotive location Solder pin signal connection Ordering Information Part Number Description ANT-GNSSCP-TH18L1 GNSS ceramic patch antenna with pin-type solder connection Available from Linx Technologies and select distributors and representatives.ANT-GNSSCP-TH18L1 Product Brief Electrical Specifications GPS L1, GALILEO E1, GNSSCP-TH18L1 GLONASS II L1, Beidou B1- Beidou B1-2 GLONASS II L1 BOC, QZSS L1 Center Frequency 1575.42 MHz 1589.74 MHz 1602 MHz Frequency Range 1567.24 MHz to 1583.60 MHz 1587.69 MHz to 1591.79 MHz 1593.31 MHz to 1608.68 MHz VSWR (max) 2.8 3.2 2.9 Peak Gain (dBi) 5.1 2.8 4.0 10 Deg.

Electrical specifications and plots measured with a 70 mm x 70 mm (2.76 in x 2.76 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. 5 40 4 30 3 20 2 10 1 0 1560 1570 1580 1590 1600 1610 Frequency (MHz) Figure 1.
