Abstract
A chip component with dielectric substrate and plurality of radiating antenna elements on the surface thereof. In one embodiment, two (2) substantially symmetric elements are used, each covering an opposite head and upper surface portion of the device. The surface between the elements comprises a slot. The chip is mounted on a circuit board (e.g., PCB) whose conductor pattern is part of the antenna. No ground plane is used under the chip or its sides to a certain distance. One of the antenna elements is coupled to the feed conductor on the PCB and to the ground plane, while the parasitic element is coupled only to the ground plane. The parasitic element is fed through coupling over the slot, and both elements resonate at the operating frequency. The antenna can be tuned and matched without discrete components, is substantially omni-directional, and has low substrate losses due to simple field image.
