The W3216 is a compact GNSS patch antenna that supports both the 1.57542 GHz and 1.598-1.606 GHz frequency bands. It features Right-Hand Circular Polarization (RHCP) and a nominal impedance of 50 Ω. The antenna provides a typical RHCP Zenith Gain of -2 dBic and a combined Zenith Gain of 2 dBi for both frequency ranges, with a typical efficiency of 60% when measured on a 50x50mm ground plane. Housed in a compact 13x13x5 mm package, the W3216 operates reliably across a wide temperature range of -40°C to +85°C. Its dual-band capability and small form factor make it well-suited for various space-constrained GNSS applications, including tracking and navigation devices.
