First High Gain, Embedded Antenna for WLAN Applications
Posted: 19-Mar-2003 [Source: SkyCross]

[SkyCross introduces industry's first antenna providing complete coverage for all frequency bands designated for WLAN communications worldwide.]

Melbourne, Florida -- SkyCross, a leading developer of advanced wireless antenna solutions, introduced the industry's first antenna that provides complete coverage for all frequency bands designated for wireless LAN communications throughout the world. The 2.4GHz band is extensively used to implement the IEEE 802.11b standard, with 802.11g soon to be approved for use in the same band. The 5 GHz bands allow for faster wireless data transmission speeds, up to 54 Mbps using the 802.11a standard. 802.11a is implemented in various 5GHz bands worldwide, including newly licensed 4.900-5.090 GHz bands in Japan.

Current WLAN antennas are limited in the range of frequency bands they can cover. Presently, only portions of these bands are covered, but not the entire bandwidth. SkyCross' new antenna provides complete coverage over all the multiple frequency bands designated for WLAN applications. SkyCross also produces these antennas in a wide variety of patterns, and physical realizations to suit all WLAN Manufacturers needs.

"This antenna design ensures that users can access any type of Wi-Fi wireless network anywhere in the world with absolutely no need for additional antennas or hardware, providing transparent worldwide Wi-Fi access," said Chris Morton, CEO of SkyCross. "This is a great benefit to both the end user who can purchase one device that will work anywhere, as well as the manufacturer who can use one standard antenna that will work with any radio standard."

Key Specifications of SkyCross' new antennas include: # Frequency Ranges: 2.4 - 2.5 and 4.9 - 5.9 GHz # Gain: 3.0 dBi Peak # Efficiency: Greater than 70% # Size: Less than 0.75" square

"Standard antenna technologies such as ceramic or PIFA antennas provide coverage for specific and narrowly defined frequency bands. As a result, these antennas cannot provide adequate multi-frequency operation without a tradeoff in performance, efficiency and/or cost," said Kerry Greer, VP of Business Development for SkyCross. "As more and more frequency bands are being allocated for WLAN use, more and more equipment manufacturers are turning to SkyCross to solve their antenna problems."
