Summary of the technology
a new GPS/GNSS antenna that performs well across GPS L1, L2, and L5 frequencies, as well as throughout the GNSS band. Multi-band GPS antenna that operates at L1, L2, and L5
Planar printed-circuit design with simple integration and conformability if required
Employes metamaterial-based electromagnetic bandgap structure (MTM-EBG), enabling rapid design for arbitrary frequency bands and communications applications
Details of the Technology Offer
The antenna is constructed using a single printed-circuit-board (PCB) layer containing the multi-band patch radiator, separated from a groundplane by an affordable 3D printed spacer made from standard polylactic acid (PLA) material, resulting in a low-profile design with a height of less than 1cm. This GPS antenna addresses the narrowband issue with the use of a 3D-printed dielectric and eliminates the need for large lumped capacitors by printing compact parallel-plate versions by using both sides of the thin patch substrate. The design allows power from a single input port to be divided four ways with good performance across all GPS/GNSS bands. This GPS antenna is particularly well-suited to applications with high multi-pathing, for example, on vehicles in dense urban centers, or for military applications where jamming and spoofing are an operational risk.
