Abstract :
A novel topology, based on the PTMA, is investigated in view of UWB WBAN applications. It is shown that adding carefully placed slots in the antenna offers a lot of advantages. The study presented treats all aspects that are important. First, the specifications in the frequency domain are met for the lower UWB band. Secondly, the design is made such that a small size is obtained. Thirdly, and very important, the presence of the human body is investigated. Finally, the pulse distortion in the frequency band 4-7 GHz is investigated and found to be low. The main conclusion is that this PTMA type is a very good topology for UWB applications in combination with human bodies.
