Abstract (en)
The antenna (10) includes an antenna unit comprising: a first dielectric body (2); a first grounding conductor body (1) provided on a lower side of the first dielectric body (2); a current supply line (5) in a form of a strip line provided on an upper side of the first dielectric body (2); a patch shaped radiative element (4) provided on the upper side of the first dielectric body (2) at an end of the current supply line; a second dielectric body (21) formed on the upper side of the first dielectric body (2) over the radiative element (4) and the current supply line (5); and a second grounding conductor body (11) provided on the upper side of the second dielectric body (21), which has a slot (3) at a position located directly above the radiative element (4); wherein the radiative elements (4) and the slots (3) of the plane antenna are arranged in a planar array with a constant interval (d) 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. <IMAGE>
