Communication terminal apparatus

A communication terminal apparatus comprising:

• a substrate disposed inside a housing, the substrate including a substrate surface occupying the most surface area of any surface of the substrate;
• a power feeding part disposed in the substrate;
• and
• a monopole antenna having a first element configured to resonate at first frequency, a second element configured to resonate at second frequency and one end connected to the power feeding part for feeding power to the first element and the second element, wherein
• the first element and the second element are substantially perpendicular to the substrate surface;
• an open end between the first element and the second element, wherein
• the communication terminal apparatus has a front surface that faces a user when the terminal is placed adjacent the user's head during use and a back surface that faces away from the user when the terminal is placed adjacent the user's head during use, and
• the open end being closer to the back surface than the open end is to the front surface.
