2.4GHz / 5GHz MID Chip Antenna Molex 146175 series Molded Interconnect Device (MID) Chip Antenna requires no ground-place clearance and features a frequency of 2.4GHz / 5GHz. This Wi-Fi®-ready Molex MID chip antenna enables wireless device makers to achieve cost-effective designs with higher levels of product integration and fewer components. The gold over nickel traces on the Molex 146175 MID antenna act as transducers that convert unguided electromagnetic waves to guided electromagnetic waves and vice versa. The Laser Direct Structuring (LDS) formed circuitry yields high, consistent RF performance. And the MID housing withstands high reflow temperatures during assembly processing.
