Wearable Circularly Polarized Rectangular Ring-Slot Antenna With Chamfered Corners
MetadataShow full item record
This paper deals with a circularly polarized rectangular ring-slot antenna with chamfered corners designed for 5.8 GHz ISM frequency band for off-body communications. The antenna, originally designed for conventional microwave substrate, has been redesigned for a soft-shell textile material to create its wearable version. For its manufacturing, the screen printing technology has been exploited. Experimental results prove that the wearable version of the antenna located on a muscle equivalent phantom achieves the impedance bandwidth more than 6.3 % for the reflection coefficient less than -10 dB, the axial ratio (AR) bandwidth 1.7 % for the AR less than 3 dB and the RHCP gain more than 6.0 dBi.
