Antenna apparatus |
摘要 |
Disclosed is a flat-type antenna apparatus which has a radiating conductor and a reference conductor disposed opposite to each other and performs feeding between the radiating conductor and the reference conductor at a position offset from the center of the radiating conductor center. The antenna includes: an insulative material layer which has relative magnetic permeability greater than 1 and is placed in a gap between the radiating conductor and the reference conductor; and a short-circuiting conductor which is disposed at a position to suppress unintended excitation and enables electric conduction between the radiating conductor and the reference conductor.
