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)
• 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)

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

Technology Applicationan 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

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
