Planar antennas composed of finite periodically structured surfaces have been studied. Two differently sized periodic structures were measured and compared in terms of their radiation characteristics...
Impedance measurement of a dipole above a periodically structured reflective surface (2008)
Schühler, M., Volmer, C., Wansch, R., Hein, M.
The impedance of a horizontal dipole antenna placed closely above a periodically structured reflective surface was determined. In order to characterize the antenna directly at its feed point, a...
Switched-line phase shifters with RF-MEMS and PIN-diodes (2006)
Schmidt, C., Schühler, M., Wansch, R., Weber, J., Hein, M.
This paper presents the examination and the comparison of two switched-line phase shifters operating in the 2.4-GHz ISM-Band. For the first realisation common pin-diodes were used as switching...
