Plane antenna with high gain and antenna efficiency |
摘要 |
A plane antenna with high gain and antenna efficiency. The antenna includes an antenna unit comprising: a first dielectric body; a first grounding conductor body provided on a lower side of the first dielectric body; a current supply line in a form of a strip line provided on an upper side of the first dielectric body; a patch shaped radiative element provided on the upper side of the first dielectric body at an end of the current supply line; a second dielectric body formed on the upper side of the first dielectric body over the radiative element and the current supply line; and a second grounding conductor body provided on the upper side of the second dielectric body, which has a slot at a position located directly above the radiative element; wherein the radiative elements and the slots of the plane antenna are arranged in a planar array with a constant interval in two orthogonal directions, where the constant interval has a value equal to 0.72 to 0.93 or more preferably 0.85 to 0.93 times a wavelength corresponding to a central frequency of a frequency band for waves to be used.
