DUAL-BAND INVERTED-F ANTENNA APPARATUS PROVIDED WITH AT LEAST ONE ANTENNA ELEMENT HAVING ELEMENT PORTION OF HEIGHT FROM DIELECTRIC SUBSTRATE

摘要

An antenna apparatus includes firs and second antenna elements. The first antenna element operates as a loop antenna that resonates at a first wavelength, and the antenna apparatus operates as an inverted-F antenna that resonates at a second wavelength. The first antenna elements includes a first element portion formed to have a predetermined height from a surface of a dielectric substrate, and the second antenna element includes a second element portion which is formed to be substantially parallel to the first element portion at least at a predetermined distance apart from the first antenna element.
