Abstract
An antenna system is provided that includes at least one driven radiator element and at least one coupling device. The at least one driven radiator element is disposed above a printed circuit board. The at least one coupling device has a step feature in at least one of width and diameter. A smaller of the at least one of the width and diameter is received in at least one of a via and slot in the printed circuit board. The at least one coupling device is oriented nominally orthogonal to a plane of the printed circuit board. The at least one solder joint couples the at least one coupling device to the printed circuit board. At least one ground plane layer is electrically connected to the at least one coupling device by at least one of the solder joint and the at least one of a via and a slot.
