Laird Receives Patent for Multiple Antenna Multiplexers, Demultiplexers and Antenna Assemblies

Laird Technologies was awarded a patent by the U.S. Patent Office. A patent was issued for work with multiple antenna multiplexers, demultiplexers and antenna assemblies. The technology reduces the number of cables required in a long cable harness (mostly in the OEM automotive market). The technology can also be used in tandem with a demultiplexer of the same nature to separate the combined signals into multiple receivers. It reduces cost by reducing the number of cables required.

The patent was awarded for the work of three of Laird Technologies’ wireless and M2M inventors: Joseph Combi (RF Engineer III), Ayman Duzdar (Director of Engineering), and Gary Reed (RF Engineer III). Their work with multiple antenna multiplexers, demultiplexers and antenna assemblies resulted in U.S. Patent #8045592.

The multiplexers and assemblies receive signals from the multiple antennas in a system and combines those signals for transmission into a single output. The demultiplexers receive the single input, and output the signal onto separate receivers. The antennas used in this patent included GPS (1574 to 1576 MHz) and world cell frequencies (824 to 960 MHz and 1710 to 2170 MHz).

The antenna multiplexers are ideal for any market where multiple antenna signals are being delivered from one antenna module to multiple receiver modules, and where GPS and cell functionality is required.
