Abstract

In this paper, the effect of user’s body is studied over previously proposed antenna. The effect of “Specific Anthropomorphic Mannequin (SAM) head and PDA hand (Talk mode)”, “Personal Digital Assistants (PDA) hand (Data mode)”, and “Dual hands (Read mode)” are studied for diversity performances. There are two different positions of the antenna over mobile circuit board is considered i.e., antenna at the top position and bottom position of the mobile circuit board. In the user proximity, the optimal location of the antenna over circuit board is chosen for real application based on the antenna performance parameters i.e. diversity parameters. The specific absorption rate (SAR) for American standard (1.6W/kg average over 1g tissues) and European standard (2W/kg average over 10g tissues) is calculated for the top and bottom position of the MIMO antenna elements and it is found that the values of SAR are well below the standard limit of FCC as well as European standard. Based on the study, it is found that antenna at the top position of mobile circuit board shows overall better performance in the presence of user’s body.

MIMO应用中紧凑型PIFA的用户接近分析

本文研究了用户身体对现有天线的影响。研究了“特定拟人化人体模型(SAM)头+ PDA手(说话模式)”、“个人数字助理(PDA)手(数据模式)”、“双手(阅读模式)”的多样性表演效果。在移动电路板上考虑有两种不同位置的天线，即天线位于移动电路板的顶部位置和底部位置。在用户接近的情况下，根据天线的性能参数即分集参数来选择实际应用中天线在电路板上的最佳位置。对MIMO天线单元的上下位置分别计算了美国标准(1.6W/kg平均超过1g组织)和欧洲标准(2W/kg平均超过10g组织)的比吸收率(SAR)，发现SAR值远低于FCC和欧洲标准的标准限值。通过研究发现，在用户身体存在的情况下，移动电路板顶部位置的天线整体性能更好。
