Title:
COMPOSITE PATCH ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/086480
Kind Code:
A1
Abstract:
[Problem] To provide a composite patch antenna that can achieve a reduction in size, has wideband performance, and is usable when embedded in a dashboard or pasted on glass. [Solution] The composite patch antenna according to the present invention is able to receive signals over multiple frequency bands, and is provided with a circuit board 10, a gap-type patch antenna 20, and a dielectric patch antenna 30. The gap-type patch antenna 20 has a radiant element 21 which is disposed in parallel with respect to the circuit board 10 with a prescribed air gap G therebetween, and in which a hole 25 is formed to penetrate substantially the center thereof. The dielectric patch antenna 30 is laminated over the radiant element 21 of the gap-type patch antenna 20 in such a manner as to be electrically insulated therefrom, and has a second power supply line 33 that is connected to a radiation electrode 32 and that penetrates a through-hole 34 in a dielectric layer 31 and the hole 25 in the radiant element 21 of the gap-type patch antenna 20 so as to be connected to a second power supply unit 13 in the circuit board 10.
