Title:
ANTENNA MODULE
Document Type and Number:
WIPO Patent Application WO/2016/063758
Kind Code:
A1
Abstract:
A first layer of a dielectric substrate includes a first dipole antenna, and a second layer includes a second dipole antenna which excites waves polarized in a direction orthogonal to that of the polarized waves excited by the first dipole antenna. Power is supplied from a first power supply line to the first dipole antenna. Power is supplied from a second power supply line to the second dipole antenna. The operating frequency of the first dipole antenna is the same as the operating frequency of the second dipole antenna. The distance from an intermediate point between two power supply points of the first dipole antenna to an intermediate point between two power supply points of the second dipole antenna is less than or equal to the effective wavelength of the operating frequency. The first power supply line and/or the second power supply line has a triplate structure. The provided antenna module can reduce coupling between the antennas due to the power supply lines even if the two dipole antennas are arranged on the substrate separated by an interval of less than or equal to the wavelength corresponding to the operating frequency.
