First Open-Ended RF Sleeve for Frequencies in UHF to Microwave

Tue, 11/27/2012 - 5:29am

 The Venti Sleeve The Venti™ RF suppression sleeve is a patent-pending EMI/RFI solution that replaces the need for higher costing 1/4 wave chokes, stubs and ferrite cores. The Venti™ sleeve is effective at 2.4 and 5 GHz and all other frequencies above 1 GHz, opening up a whole new world for product designers and engineers that was not previously available. A small form, low labor replacement for current EMI/RFI alternatives available today, the Venti™ sleeve is perfect for mass-produced coax and cables.

Venti™ R&D engineers, while developing Horizontal WiFi antenna designs, discovered that the radiating coaxial feedlines distorted their antenna patterns. Suppressing radiating feedlines in 2.4 & 5 GHz, engineers had to look beyond the prior art for a more cost effective solution.

The Venti™ engineers developed an EMI/RFI Suppression sleeve for RF Coax/Cables for antennas, consumer electronics, computer and power cables. The Venti™ sleeve suppresses coax and cable radiation (EMI/RFI) that distorts antenna patterns and affects components and devices inter-connected by cable assemblies.

The Venti™ sleeve is effective from 500MHz to 30GHz and is very low profile. The Venti™ sleeve is a choke sleeve that may be simply and economically applied, it eliminates the need for connection to the cable, and does not require the cable to be coaxial or shielded. The low-cost tuned Venti™ sleeve is targeted to specific frequencies and can be applied as mass produced conductive foil or conductive coating. There is no need for any redesign of coax, cables or connecting components or devices to implement the sleeve - in fact, current coax and cables can be retrofitted with the sleeve.
