Multi-band antenna and mobile communication terminal having the same
First Claim
1. A mobile communication terminal comprising:
- a dielectric substrate;
a ground surface formed on a first area of the dielectric substrate;
a radiation part disposed on a second area of the dielectric substrate where the ground surface is not formed, at a predetermined distance from the dielectric substrate, the radiation part having first and second slots formed thereon;
a feeding line formed on the second area of the dielectric substrate and having one end connected to the radiation part;
a ground line disposed on the second area of the dielectric substrate at a predetermined distance from the feeding line and having one end connected to the radiation part and another end connected to the ground surface; and
a matching ground surface formed on the second area of the dielectric substrate, the matching ground surface disposed in a superimposed relationship with a portion of the radiation part and extending from the ground surface to be capacitively coupled to the radiation part.
