Antenna device having a capacitive loading element

An antenna device comprising:

• a case;
• and
• a first antenna and a second antenna provided in the case, wherein
• the second antenna includes a capacitance loading element,
• the capacitance loading element includes a turning-around area turning around in a front-rear direction on at least one of a front side and a rear side thereof,
• when the turning-around area is provided on the front side, at least part of a transmitting portion and/or a receiving portion of the first antenna is situated in front of the turning-around area of the capacitance loading element,
• when the turning-around area is provided on the rear side, at least part of the transmitting portion and/or the receiving portion of the first antenna is situated behind the turning-around area of the capacitance loading element, and
• when the turning-around area is provided on the front side and on the rear side, at least part of the transmitting portion and/or the receiving portion of the first antenna is situated at least one of in front of the turning-around area on the front side of the capacitance loading element and behind the turning-around area on the rear side of the capacitance loading element.
