Abstract :
A three-dimensional cavity backed coplanar waveguide fed ultra-high frequency (UHF) antenna is presented. The antenna is designed to operate in microwave system for heart failure detection. A parasitic cavity is used to increase the bandwidth of the antenna, resulting in a fractional bandwidth of 30 % (737-1001 MHz). The antenna has a gain that varies between 3 to 5.25 dBi through this band. Due to its broadband characteristics, compact size and suitable gain, the proposed antenna is a good candidate for the detection of fluids accumulation in the lungs, which is an indication of heart failure.
