Millimeter Wave Antennas for Wearable Applications

Abstract

In this chapter the authors will be discussing about what wireless body area networks(WBAN) are, where are they used, what are the advantages of using millimeter wave frequencies, and novel millimeter wave antenna design suitable for wearable applications using CST software. The specific frequency that is used in the millimeter wave frequency is 60GHz with bandwidth of 7 GHz. Results from simulation are satisfactory in terms of gain and effectiveness. The performance of millimetre wave antennas is less affected by the presence of a human body because of their miniature-like dimensions and shallow penetration depth into human body layers. This makes them perfect for body-centric wireless communication (BCWC) applications. The essential property data was thus used to virtually generate a human body model. The antenna is kept close to the created human body model as simulations are run again at the same frequencies as previously. The results were promising as the VSWR and return loss curves remained almost identical.
