Wideband antennas
First Claim
1. A wideband dipole type antenna comprising a substrate presenting first and second faces, a first conductor arm and a second conductor arm placed on the first face of the substrate, a feeder line supplying the first and second conductor arms by electromagnetic coupling, the feeder line extending from a transition point to a feed circuit by passing under the first conductor arm, wherein the antenna includes a filtering means formed by a line element that extends the feeder line beyond the transition point between the first conductor arm and the second conductor arm and is placed under the second conductor arm, the line element having a length of λ
- g/2 where λ
g is a wavelength guided in the line element for a frequency band to reject.

Abstract
The invention relates to a dipole type wideband antenna comprising a substrate presenting two faces, a first conductive arm, a second conductive arm placed on the substrate, a feeder line supplying the second arm passing under the first arm, In this case, the feeder line extending by a line element placed under the second arm, this element being dimensioned to filter a given frequency.
