A wide bandwidth, body contact, directive beam, circularly polarized, and single arm Archimedean spiral antenna with an integrated coupler is proposed for radiometric temperature measurement inside a human body at S-band. An innovative integration of two functions in one configuration is done in a straightforward design. The coupler consists of 50 Ω grounded coplanar waveguide placed under the active region of the spiral antenna. After determination of the effective dielectric constant of the… CONTINUE READING
