Chipantenn samt antennanordning och apparat för mobilkommunikation innefattande en sådan chipantenn

摘要

The invention provides a chip antenna comprising: a substrate made by laminating a plurality of sheet layers made of ceramic; a radiating conductor having substantially planar shape and provided on said substrate; a grounding conductor having substantially planar shape and provided so as to oppose said radiating conductor with said sheet layers interposed in between; a capacitor conductor having substantially planar shape and provided so as to oppose said radiating conductor and said grounding conductor with said sheet layers interposed in between; a first shorting conductor which connects said radiating conductor and said grounding conductor; a second shorting conductor which connects said grounding conductor and said capacitor conductor; a feed terminal connected to said radiating conductor or said capacitor conductor; and a ground terminal connected to said grounding conductor. According to the above a chip antenna, the resonance frequency can be adjusted readily with compact size can be achieved.
