1. A communication device, comprising:
- a first antenna;
a second antenna;
a ground element, coupled to a conductive plane; and
an isolation element, disposed between the first antenna and the second antenna, and comprising a first portion and a second portion, wherein a first end of the first portion and a first end of the second portion are respectively coupled to the ground element, the first portion faces to the first antenna, the second portion faces to the second antenna, and a second end of the first portion is spaced apart a coupling distance from a second end of the second portion,wherein the communication device is operated in at least a first communication band and a second communication band, a frequency of the first communication band is lower than a frequency of the second communication band, and the first portion and the second portion of the isolation element resonate respectively in the first communication band and the second communication band so as to improve isolation between the first antenna and the second antenna in the first communication band and the second communication band.
