Multiband planar antenna and electronic equipment

Electronic equipment comprising:

• a multiband planar antenna including:
• an insulating film;
• a first antenna section formed on the film;
• and a second antenna section formed on the film, the second antenna being placed so as to face to the first antenna section across a feeding point,
• wherein the first antenna section includes:
• a first antenna element including a side having a length in an extending direction corresponds to a first resonance frequency, the first antenna element having a band-like shape;
• a second antenna element placed at a predetermined distance from the first antenna element so as to be in parallel with the first antenna element, the second antenna element being shorter than the first antenna element and having a band-like shape;
• and a first coupling section to couple the first antenna element with the second antenna element, wherein a length in the extending direction of a first clearance corresponds to a resonance frequency higher than the first resonance frequency, the first clearance being a portion of the first antenna section between the first antenna element and the second antenna element and corresponding to a length in the extending direction of the second antenna element except the first coupling section, and
• wherein the second antenna section includes:
• a third antenna element including a side having a length in an extending direction corresponds to the first resonance frequency, the third antenna element having a band-like shape;
• a fourth antenna element placed at a predetermined distance from the third antenna element so as to be in parallel with the third antenna element, the fourth antenna element being shorter than the third antenna element and having a band-like shape;
• and a second coupling section to couple the third antenna element with the fourth antenna element, wherein a length in the extending direction of a second clearance corresponds to a resonance frequency higher than the first resonance frequency, the second clearance being a portion of the second antenna section between the third antenna element and the fourth antenna element and corresponding to a length in the extending direction of the fourth antenna element except the second coupling section;
• a communication section to perform wireless communication with external equipment through the multiband planar antenna;
• and
• a control section to control the communication section.
