Abstract:
1. An antenna apparatus comprising a dipole antenna, a first monopole antenna and a second monopole antenna, each formed in a form of a conductor pattern on an insulating substrate, wherein the dipole antenna includes: a first antenna element including a first portion that has one end connected to a first feeding point and extends in a predetermined first direction, and a second portion that has one end connected to another end of the first portion and extends in a predetermined second direction; and a second antenna element including a third portion that has one end connected to a second feeding point and extends in the first direction, and a fourth portion that has one end connected to another end of the third portion and extends in a predetermined third direction, wherein the first monopole antenna includes a fifth portion that has one end connected to a third feeding point and extends in the second direction, and a sixth portion that has one end connected to another end of the fifth portion and extends in the first direction, wherein the second monopole antenna includes a seventh portion that has one end connected to a fourth feeding point and extends in the third direction, and an eighth portion that has one end connected to another end of the seventh portion and extends in the first direction, wherein each of the fifth and seventh portions is formed to be adjacent to and to be substantially parallel to a conductor provided outside the antenna apparatus, wherein the fifth portion includes a first loop portion, and wherein the seventh portion includes a second loop portion.
