Title: Antenna construction including a ground plane and radiator

Abstract: An antenna construction according to the invention has a radiator, ground plane and at least one matching element. The matching element is capacitively coupled to a ground potential. By varying the number, location and strength of the capacitive coupling of the matching elements the characteristics of the antenna construction, such as the number of resonance frequencies, resonance frequencies and radiator impedance at the feed point can be controlled in a versatile manner.
