Mobile phone having a directed beam antenna
View Patent ↗A mobile phone includes a body and an antenna array that is coupled to the body.
1. A mobile phone comprising:
a body;
a first pair of parallel dipoles, spaced apart and positioned within the body in order to focus electromagnetic energy away from a user's head during operation; and
a retractable antenna element wherein the retractable antenna element being used as a whip antenna while in an extended position and being forming an antenna array incorporating the first pair of parallel dipoles while in a retracted position.
2. The mobile phone of claim 1 , one of the dipoles of the first pair of dipoles is a metallic paint or a line of metal.
3. The mobile phone of claim 1 further comprising:
a second pair of parallel dipoles, spaced apart and positioned within the body in order to focus electromagnetic energy away from the user's head during operation, the second pair of dipoles orthogonal to the first pair of dipoles in order to achieve orthogonally polarized electromagnetic fields during operation.
4. The mobile phone of claim 1 further comprising:
a loop antenna coupled to the body in order to achieve orthogonally polarized electromagnetic fields during operation.
