Antenna structure and mobile terminal having antenna structure

A mobile radio apparatus comprising:

• a case;
• a rod antenna;
• an antenna supporting unit configured to enable the rod antenna to be extracted out of and retracted into the case
• a flexible substrate arranged around the antenna supporting unit;
• an antenna pattern formed on the flexible substrate;
• a radio unit configured to transmit and receive a radio signal;
• and
• a matching circuit formed on the flexible substrate, the matching circuit being configured to be continuously capacitivley coupled with the antenna pattern, wherein
• the rod antenna and the matching circuit are configured to capacitivley couple the rod antenna and matching circuit together only when the rod antenna is extended from the case.

A mobile radio apparatus comprising:

• a case;
• a rod antenna having a first central axis;
• an antenna supporting unit configured to enable the rod antenna to be extracted out of and retracted into the case;
• a flexible substrate arranged around the antenna supporting unit;
• an antenna pattern formed on the flexible substrate and having a second central axis, the first central axis and the second central axis crossing at an angle in the range of 45° to 90°;
• a radio unit configured to transmit and receive a radio signal;
• and
• a matching circuit formed on the flexible substrate, the matching circuit being configured to be continuously capacitively coupled with the antenna pattern, wherein
• the rod antenna and the matching circuit are configured to capacitively couple the rod antenna and matching circuit together only when the rod antenna is extended from the case.
