Abstract
A Frequency and Polarization Agile Disc Monopole Wearable Antenna for Medical Applications
Highlights
Body-centric wireless communication system has attracted significant interest during the past several decades
Antenna system having multiple capabilities and functions with small occupied volume is the general demand of any modern wireless communication system
A frequency reconfigurable antenna for bluetooth, WiMAX, and WLAN applications has been proposed in [5] that can adjust its operating band according to the requirement
Summary
Body-centric wireless communication system has attracted significant interest during the past several decades. The ground plane of the coplanar waveguide fed monopole antenna as proposed in [7] has been modified by introducing an L-shaped stub on the either side of the monopole along with PIN diode to achieve polarization reconfigurability. Three polarization states LHCP, RHCP, and LP have been achieved using two pin diodes in a simple circular metal ring antenna with a modified ground plane [9]. A frequency reconfigurable Denim material based textile antenna has been reported in [13] that operates in ISM and WLAN band. PIN diode is used to tune the antenna between these two operating bands with simple biasing circuitry Another approach has been reported in [16] that realizes two different types of polarization in a frequency reconfigurable antenna. The simulated and measured performances of the antenna have been presented
