Abstract
An electronic device is disclosed which has a diversity type of antenna unit constituted by three antennas and comprises a dual-band wireless communication function. The antenna unit has two transmission-receiving antennas adapted to each of different frequency bands, and one receive-dedicated antenna.
Claims13
An electronic device comprising:
- two transmission-receiving antennas respectively adapted to different frequency bands;
- a receiving antenna for the frequency bands which forms two diversity antennas together with the transmission-receiving antennas;
- and
- a wireless communication unit, connected to the transmission-receiving antennas and the receiving antenna, which performs wireless communication in each of the frequency bands.
1 more element
An electronic device comprising:
- a display unit which hold a display panel;
- an antenna unit including three antennas provided at a portion of the display unit;
- and
- a wireless communication unit which is connected to the antennas and achieves a wireless communication function in first and second frequency bands,
- wherein the antenna unit has:
- two transmission-receiving antennas respectively adapted to the first and second frequency bands;
- and
- a receiving antenna for the frequency bands and disposed at a predetermined distance from each of the transmission-receiving antennas, thereby constituting a diversity antenna adaptive to the frequency bands.
5 more elements
