This paper investigates the hand-hold implications on the electromagnetic coupling between human head and cellular phones. FDTD-method has been used to evaluate both the antenna performance and the induced SAR in head as caused by different phone models held at different hand positions. Bar-type and clamshell-type phones having external and internal antennas are used to simulate their electromagnetic...
This paper presents a design of a single coaxial-feed stacked rectangular microstrip patch antenna (MPA) with shorting pins. The proposed MPA design is based on the multilayer structure technique, and the cellular hand-set plastic cover is put as a one layer of the MPA structure layers. A finite- element based solver has been used to achieve the proposed design. This stacked MPA can cover most of...
