摘要： An antenna device includes: a dielectric substrate 1; a first conductor 2 provided on a first surface of the dielectric substrate 1; a second conductor 100 provided on a second surface of the dielectric substrate 1, the second surface being opposite to the first surface on which the first conductor 2 is provided, the second conductor 100 having a feeding point 12; a third conductor 200a provided on the same second surface on which the second conductor 100 is provided; and a pair of transmission lines that electrically connect the second conductor 100 and the third conductor 200a.

摘要： A signal combiner (33) specifies a weighting coefficient w for suppressing a grating lobe included in a composite signal S3 obtained when combining a digital received signal S1 and digital received signal S2 stored by a signal calculation storage (31), from the gain in a grating lobe direction in a first radiation pattern and the gain in a grating lobe direction in a second radiation pattern, and combines the digital received signal S1 and digital received signal S2 stored by the signal calculation storage (31) using the weighting coefficient w.

摘要： The antenna device includes: an element part 100 having an excitation element 1, a first passive element 11 having first and second conductive parts 11a and 11b, a second passive element 21 having third and fourth conductive parts 21a and 21b, a first switch 12 controlling conduction between the first and second conductive parts, and a second switch 22 controlling conduction between the third and fourth conductive parts; and a controller 200 outputting an electric signal for controlling conduction of the first and second switches. The controller outputs identical DC signal to the first and second switches, and one of the first and second switches is brought into conduction while the other one is brought out of conduction.
