  2. Advanced Antenna Technology for Ubiquitous Communication in Mobile Computing Devices Presented by: Paul Tornatta Chief Technical Officer SkyCross, Inc.

  3. Company Overview Founded in 2000, SkyCross is a global designer and manufacturer of one-stop antenna solutions for a variety of wireless devices Mobile Phones Networking Handsets Smartphone Femtocell Access point Router Ask us about other devices – our technology is versatile! Computing Personal/Home Entertainment USB dongle Personal Navigation Device PC Card Personal Media/Game Players Ultra-mobile PC Laptop Wireless Audio Home Entertainment Our multi-band/mode antennas enable increased functionality – voice, data, video, location, audio – in any wireless device without compromising style.

  4. The Antenna Challenge for Mobile Devices • Antenna design implementation must obey the laws of physics • Volume / efficiency / bandwidth trade • Isolation / mutual coupling in multiple antenna implementation • Correlation coefficient • Expansion of service for mobile devices (multi-band antenna problem) • Multi-band, multi-mode functionality • Reduction of physical space for antennas • Slim industrial designs • Diversity and MIMO application (multiple-antenna problem) • Head and hand effect detuning

  5. Expansion of Services for Mobile Devices Voice/Data • 802.11 a/b/g/n (diversity/MIMO) • WiMAX (MIMO) • Bluetooth • 800, 1900, 2100 MHz with diversity Rx • GSM 900, 1800 MHz • AWS 7-7 (700 MHz) band with 4G (MIMO) • AWS 17-21 band with 4G (MIMO) Video / Audio • Video (VHF, UHF) (diversity) • FM Radio Location • GPS Other • Near Field Communications (RFID)

  6. Emerging Requirements for embedded antennas – “a real mess” • Non-voice services are driving multi-band diversity solutions for 3G • In particular WIMAX and LTE specify multiple antennas (MIMO) • Mobile video is wide band and low frequency making it difficult to implement with embedded antennas Diversity / MIMO “antenna pairs” spread out on the phone for improved isolation This antenna configuration is expensive and inefficient (poor performance) WiFi 802.11 n / BT/ WiMax 2400-2700 MHz 700/850/1900/2100 MHz Diversity (MIMO LTE) GPS 1575 MHz WiFi 802.11n / WiMax (MIMO) 2400 MHz Could be any mobile video standard DVB-H 470-870 MHz DVB-H (Diversity) 470-870 MHz Hexa-Band Cellular 700/850/900/ 1800/1900/2100 MHz Diversity / MIMO Antennas Single Feed Antenna Structures

  7. iMAT iMAT iMAT Technology Application:“an elegant solution” • Isolated Mode Antenna Technology (iMAT) allows diversity and MIMO antennas to be combined into single dual-feed antenna structures – reduced size, lower cost, improved performance • Switch tuning technology allows antennas to be made smaller – reduced size by 50%, improved performance by 2-3 dB Dual-Feed WiFi 802.11 n / BT/ WiMax 2400-2700 MHz WiFi 802.11n / WiMax (MIMO) 2400 MHz This level of integration and size reduction is not possible without SkyCross Technology DVB-H 470-870 MHz Could be any mobile video standard Dual-Feed DVB-H (Diversity) 470-870 MHz 700/850/1900/2100 MHz Diversity (MIMO LTE) +GPS 1575 MHz Hexa-Band Cellular 700/850/900/ 1800/1900/2100 MHz Dual-Feed iMAT Dual-Feed Antenna Structures

  8. Antenna Concept – Mobile Internet Device (MID) Platform • Six antennas in brow space • 1&2: WWAN antennas + GPS (850/900/1800/1900/2100 + 1575 MHz) • 3&4: WiFi-WiMAX antennas (2.3-2.4, 2.4-2.5, 2.5-2.7 GHz + 4.9-5.9 GHz) • 5&6: uwb antennas (3.0-6.0 GHz) • All are planar antennas, can be made by FPC or sheet metal 2 4 3 8 mm 6 1 4.8 mm Display 120 mm 5 150 mm Display

  9. Conclusions • Consumers demand flexibility and performance from their devices without regard to protocol, frequency, or service provider • This requires devices to work seamlessly between a variety of carriers and protocols • Advanced antenna design techniques exist can be applied to enable solutions without sacrificing sleek industrial designs

  10. Thank You! Design Freedom to create any device with uncompromised performance and style!
