Abstract: Antenna elements for multiband antennas are disclosed. A multiband antenna is configured to operate in at least two frequency bands. The antenna element is configured to receive a signal from an unbalanced signal feed and comprises: a stalk configured to be mounted on a ground plane; at least one radiating element extending from the stalk; a balun configured to receive and convert an unbalanced signal from an unbalanced signal feed to a balanced signal and to supply the balanced signal to the at least one radiating element; and at least one resonance suppression filter. The at least one resonance suppression filter comprises an inductive component and a capacitive component arranged in parallel, and in some embodiments a resistive component in series with the inductive component.
