Abstract :
In design and synthesis of wearable antenna, the isolation of antenna and human body is always given paramount importance because this shielding has a pronounced effect on antenna parameters such as resonant frequency, input impedance and radiation pattern. This paper deals with the effects of different shapes of ground plane of quarter-wave monopole antenna on on-body communications around the human body model at 1.8 and 2.45GHz. A non line-of-sight (NLOS) situation is demonstrated. Results show that the circular ground plane is providing better communication link than square shape for monopole antenna at mentioned mobile communication frequencies.
