1. An antenna assembly comprising:
a transparent dielectric substrate;
a first area comprising an antenna on one side of the transparent dielectric substrate; and
a second area comprising a ground conductive pattern and a feed pattern,
wherein the antenna comprises:
a first conductive pattern comprising a closed loop trace comprising a first part, a second part, a third part, a fourth part, and a fifth part, wherein a first end of the first part is electrically connected to the feed pattern, a second end of the first part is electrically connected to a first end of the second part, a second end of the second part is electrically connected to a first end of the third part, a second end of the third part is electrically connected to a first end of the fourth part, a second end of the fourth part is electrically connected to a first end of the fifth part, a second end of the fifth part is electrically connected to a first portion of the ground conductive pattern, and wherein the second part and the fourth part are disposed on opposite sides of the closed loop trace, the first part and the third part are disposed on opposite sides of the closed loop trace, and the first part and the fifth part are disposed at a same side of the closed loop trace;
a second conductive pattern electrically connected to a second portion of the ground conductive pattern; and
a slot surrounded by the first conductive pattern and comprising a first slot area and a second slot area,
wherein the second conductive pattern is disposed between the first part of the first conductive pattern and the ground conductive pattern,
wherein a first gap in the first slot area is defined between a first point of an inner side of the first part near the first end of the second part and a first point of an inner side of the third part near the second end of the second part,
wherein a second gap in the first slot area is defined between a second point of the inner side of an end of the first part connected to the feed pattern and a second point of the inner side of the third part near an intermediate point along the third part, and
wherein a distance of the second gap is less than the first gap.
