Product Brief – Airborne SDIO/SPI 802.11b/g Radio 6.0 Quatech, Inc. Antenna The unit supports antenna connection through a single Hirose U.FL connector, located on the top surface of the radio next to the RF shielding. Any antenna used with the system must be designed for operation within the 2.4GHz ISM band and specifically must support the 2.412GHz to 2.482GHz for 802.11b/g operation. They are required to have a VSWR of 2:1 maximum referenced to a 50 system impedance. 6.
Product Brief – Airborne SDIO/SPI 802.11b/g Radio Quatech, Inc. TNC/SMA are not allowed (there are more that are not), RP-TNC/RP-SMA are allowed. 6.3 Host Chassis Mounted Antenna Host Chassis mounted antennas require no work on the host PCB. They utilize an antenna type called „flying lead‟. There are two types of flying leads; one which provides a bulkhead mounted antenna connector and one which provides a bulk head mounted antenna. The type you choose will be determined by the application.
Product Brief – Airborne SDIO/SPI 802.11b/g Radio Quatech, Inc. PCB Embedded – This approach embeds an antenna design into the host PCB. This approach is very common with add-in WiFi card (CF, PCMCIA, SDIO, etc.) as it requires no external connections and is the cheapest production approach. The lower production cost requires significant development cost and lack of performance and flexibility.
Product Brief – Airborne SDIO/SPI 802.11b/g Radio Quatech, Inc. Locate the antenna where there is a minimum of obstruction between the antenna and the location of the Access Points. Typically Access Points are located in the ceiling or high on walls. Keep the main antenna‟s polarization vertical, or in-line with the antenna of the Access Points. 802.11 systems utilize vertical polarization and aligning both transmit and receive antenna maximizes the link quality.
