Antenna extender, and electronic device with antenna extender

An electronic device, comprising:

• a housing having a first side and a second side,
• a dielectric cover on the second side,
• an electrically conductive peripheral structure along edges of the first side and the second side;
• an antenna feed coupled to a portion of the electrically conductive peripheral structure that is configured to use the portion of the electrically conductive peripheral structure as a radiating antenna element, wherein the portion has a first end and a second end along a longitudinal direction of the portion and the first end of the portion is an open end;
• a conductive member on or underneath the dielectric cover, wherein the conductive member has a first dimension along the longitudinal direction of the portion and extends inwards from the portion, with reference to the electrically conductive peripheral structure, by a second dimension that is less than twice the first dimension, the conductive member and the antenna feed are disposed with an interval along the longitudinal direction of the portion, the antenna feed and the second end of the portion are disposed on the same side of the conductive member;
• and
• an electric coupling between the portion of the electrically conductive peripheral structure and a part of the conductive member extends along the longitudinal direction of the portion of the electrically conductive peripheral structure.
