Abstract (en)
[origin: EP1487052A1] The arrangement has an aperture length (L) selected to be so small that the resonant frequency of the aperture (1) exceeds the center frequency of the working frequency range, a capacitive tuning element for tuning the aperture resonance to a resonant frequency close to the center frequency and a coupling element for coupling the antenna connection points to the electromagnetic fields in the aperture with minimal residual inductive effects of magnetic reactive power.
