This compact Molex molded GPS antenna is a surface-mount option for adding satellite reception to space-constrained PCB designs. It measures just 3 x 5 x 4mm and is designed for operation across a 1561 - 1602 MHz frequency range.

The antenna is a monopole type made from LDS material, with a 4x6mm PCB clearance requirement. It is suited to designs where a tiny board-mounted GPS antenna is preferred over a cabled or external antenna.

Documentation for this part includes a datasheet and mechanical drawing to help with PCB layout and integration.

Specifications:

Antenna Type: Monopole
Frequency Range: 1561 - 1602 MHz
Return Loss: <-8dB
Peak Gain: 1.1dBi
Total Efficiency: >50%
Polarization: Elliptic
Axial Ratio: <6.0

Jargon buster

Plain-language definitions for the technical terms used above.

Axial: Axial components have one lead coming out of each end, so they lie flat or span holes on a circuit board or breadboard. This matters when checking whether the resistor will physically fit your prototyping or through-board assembly method.
GPS: The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
PCB: A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
