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

Expansion of Services for Mobile Devices Voice/Data – – – – 802. 11 a/b/g/n (diversity/MIMO) Wi. MAX (MIMO) Bluetooth 800, 1900, 2100 MHz with diversity Rx GSM 900, 1800 MHz AWS 7 -7 (700 MHz) band with 4 G (MIMO) AWS 17 -21 band with 4 G (MIMO) Video / Audio – Video (VHF, UHF) (diversity) – FM Radio Location – GPS Other – Near Field Communications (RFID)

Emerging Requirements for embedded antennas – “a real mess” • Non-voice services are driving multi-band diversity solutions for 3 G • In particular WIMAX and LTE specify multiple antennas (MIMO) • Mobile video is wide band low frequency making it difficult to implement with embedded antennas Wi. Fi 802. 11 n / BT/ Wi. Max 2400 -2700 MHz GPS 1575 MHz Could be any mobile video standard DVB-H 470 -870 MHz Hexa-Band Cellular 700/850/900/ 1800/1900/2100 MHz 700/850/1900/2100 MHz Diversity (MIMO LTE) Wi. Fi 802. 11 n / Wi. Max (MIMO) 2400 MHz DVB-H (Diversity) 470 -870 MHz Diversity / MIMO Antennas Diversity / MIMO “antenna pairs” spread out on the phone for improved isolation This antenna configuration is expensive and inefficient (poor performance) Single Feed Antenna Structures

Technology Application: “an elegant solution” • Isolated Mode Antenna Technology (i. MAT) 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 d.

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: Wi. Fi-Wi. MAX 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 120 mm 150 mm Display 5

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
