A COMPACT MOBILE TELEPHONE HANDSET ANTENNA WITH REDUCED RADIATION HAZARDS

CONVENTIONAL ANTENNAS -THEIR DRAWBACKS

While in use, the handset is placed close to the head of the user, within the near field zone of the antenna where most of the electromagnetic energy is stored rather than radiated….

MICROSTRIP ANTENNAS – An ideal alternative

Antenna Design:

Radiation Patterns:

The figure indicates considerable reduction in the SAR in the quadrant facing the user. This region forms a zone of silence where the user's head can be located

Experimental Results:
