Challenges for terminal antenna engineers under multiple wireless standards

With the popularization of 3G technology and the development of wireless standards and technologies such as LTE, NFC, Bluetooth 4.0, cmms B, and MIMO, mobile Terminals need to integrate multi-band main antennas (supporting 2g, 3G, LTE and other multi-standard), as well as GPS, BT, WiFi, NFC, wireless charging and other antennas.

As a result, terminal antenna engineers are facing huge challenges:

Antenna size

-The cell phone size is getting smaller and smaller.
-The 'clear' of the antenna is getting smaller and smaller.
-Process Implementation: shrapnel-> FPC-> lDs

Multi-Antenna Coupling and Isolation Design

-Primary Antenna
-GPS, BT, WiFi, NFC, etc.

OTA Performance

-TRP-TIS-performance in different working environments (Head, hand impact, etc) EMC compatibility

Whether it meets the SAR and HAC standards

How to integrate multiple antennas in a limited space, how to ensure EMC problems in the entire environment, how to improve OTA performance, how to reduce SAR and ensure the compatibility of hearing aids (HAC. Electromagnetic Field Simulation Technology can complete various types of terminal antenna simulation calculation, multi-antenna isolation Calculation, SAR evaluation, etc. It helps antenna engineers quickly complete design and performance evaluation, reduce the number of tests, and improve R & D efficiency.

In2013 Shenzhen terminal Radio Frequency Technology SeminarEMSs China will introduce the electromagnetic field simulation technology, CMA technology and feko application of the electromagnetic field simulation software in the design of wireless terminal antennas, and introduce optenni lab, the most advanced antenna matching circuit optimization design tool.
