Abstract
A chip antenna is fabricated by forming a conductor plate having main and auxiliary antenna elements with a spacing therebetween which are connected through coupling portions to a frame surrounding the antenna elements, the conductor plate being embedded in or stacked on a dielectric chip and being cut along side faces of the dielectric chip. The main and auxiliary antenna elements have inner end edge portions that are opposed to each other over the entire width of the dielectric chip to provide a constant opposed area, suppressing a variation in antenna performance.
