A Low Profile UWB Antenna for Wearable Applications: The Tripod Kettle Antenna (TKA)

Anja Skrivervik, Roberto Torres Sánchez, Dea Dorina Cara, Jovanche Trajkovikj

A new low profile ultra-wideband (UWB) antenna for wearable applications is presented. Its structure is derived from the quadripod kettle antenna (QKA) [1], and is called tripod kettle antenna (TKA). The proposed antenna is very well suited for wearable ap ...

Double resonance spectroscopic studies using a new generation of microfabricated microwave cavity

Anja Skrivervik, Jean-François Zürcher, Maddalena Violetti

We evaluate the potential of a new generation microwave cavity by double resonance spectroscopic studies. Both, the cell and the microwave cavity are microfabricated. This allows a substantial size reduction for the physics package, without compromising th ...

Novel approach to the measurement of ultra wideband antenna efficiency

Anja Skrivervik, Nuno Miguel Faria Pires, Mohsen Koohestani

This Letter presents a new cavity-based approach for measuring the radiation efficiency of Ultra Wideband (UWB) antennas. The procedure is based on a generalized Wheeler cap method (GWCM ) that is only practical for narrowband measurements and so this Lett ...

Time-domain performance of a patch-loaded band-reject UWB antenna

Anja Skrivervik, Nuno Miguel Faria Pires, Mohsen Koohestani

A previous study of a novel technique to design a band-reject UWB monopole antenna by using patch loading is extended. Frequency-domain measurements have confirmed that the antenna designed using this technique rejects the interfering signal at the two int ...

Synthesis of uniform amplitude focused beam arrays

Juan Ramon Mosig, Anja Skrivervik, Benjamin Fuchs

An iterative algorithm to synthesize uniform amplitude focused beam arrays is presented. While the number of array elements and the excitations are fixed and known, the locations of the elements are optimized to radiate a narrow beam low sidelobe pattern. ...
