ABSTRACT:
An antenna apparatus includes an antenna block and a substrate. The antenna block has a base that is made of a substantially cuboid dielectric body, an upper-surface conductor formed on an upper surface of the base, first and second pad electrodes that are formed on both ends of a bottom surface of the base in a longitudinal direction of the base, respectively, and a lateral-surface conductor connecting the upper-surface conductor and the second pad electrode. The substrate has a region mounting the antenna block, a ground pattern provided around the mounting region, first and second lands that are provided within the mounting region so as to correspond to the positions of the first and second pad electrodes, a feed line that is connected to the first land, an impedance-adjusting pattern connecting the first land and the ground pattern, and a frequency-adjusting pattern connecting the second land and the ground pattern.
