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...
Due to miniaturization and advantages offered, RF MEMS capacitors have recently been developed for utilization in microwave circuits, i.e., wireless communication applications such as filters, matching networks, and phase shifters among others. Throughout this presented work two-plate RF MEMS capacitor networks with two different number of membranes are presented. Both are designed with the same dimension...
