Examples described herein relate to flexible antenna belts. For instance, a system may comprise a flexible antenna belt, where the flexible antenna belt is to transition between a closed position and an open position, and a flexible display coupled to the flexible antenna belt.

An antenna system having a first antenna that includes a metal middle frame, a first metal frame, and a second metal frame. The middle frame is a ground of the first antenna. The first and second metal frames are side edges of the mobile terminal. A first gap is formed by the first, the second metal frames, and the middle frame. A first end of the first metal frame is connected to the middle frame by a first connection point, and a second end of the first metal frame is connected to a first end of the second metal frame. A first slit is located between a second end of the second metal frame and the middle frame. The first feed point on the first metal frame is connected to the middle frame. A length of the first metal frame is greater than a length of the second metal frame.

A dipole antenna apparatus, and method of manufacture of such an apparatus, are provided. The antenna apparatus has a conductive plate extending in a first plane, and a pair of conductive elements arranged to form a dipole antenna, where the pair of conductive elements are located in a second plane parallel to the first plane. Each conductive element forms a conductive ring in the second plane that surrounds a non-conductive inner area. The first conductive element in the pair of conductive elements has a conductive bridge extending across the conductive ring to divide the non-conductive inner area into at least two portions. A conductive connection then extends from the conductive bridge to the conductive plate. As a result, in normal use the conductive plate acts as a reflector for the dipole antenna, but in the event of a direct current event the presence of the conductive bridge and the conductive connection causes the conductive plate to operate as a ground plane for direct current within the first conductive element of the dipole antenna. It has been found that such an approach provides a particularly efficient, low cost, design for a dipole antenna.
