Ground plane shape effects on around the body area network at 1.8GHz and 2.45GHz

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.
