To achieve dual frequency operation for Wireless Body Area Network (WBAN) applications, a hybrid dual-band dielectric resonator antenna with serpentine slot fed by a microstrip line is proposed. The proposed antenna structure consists of cylindrical dielectric resonator and serpentine slot resonator. The serpentine slot is etched on the ground plane of the Dielectric Resonator Antenna (DRA). By adjusting the structure parameters, the cylindrical dielectric resonator operates at higher band (2.4 GHz) and serpentine slot operates at lower band (403 MHz), both resonators are radiating with two different radiation patterns. The proposed antenna structure is suitable for WBAN applications.
