<p>The invention provides an antenna arranged to operate in a frequency band with a bandwidth B and a centre frequency f c . The antenna comprises a slot integrated in a vehicle structure. The slot has a first end and a second end, The antenna also comprises a feeding arrangement with a feed line and a first connection point at a first edge of the slot and a second connection point located at a position substantially across the slot from the first connection point at a second opposite edge of the slot. The slot is arranged to be shorted at the first end and open at the second end. The impedance matching is arranged by locating the feeding arrangement to a position along the slot where antenna impedance matches the impedance of an input/output of a transceiver unit.</p> |
