Abstract
An apparatus includes a wireless device having a radio frequency (RF) circuit, an omni-directional antenna coupled to the RF circuit, a directional antenna coupled to the RF circuit, and a switch configured to couple at least one of the omni-directional antenna and the directional antenna to an output of the RF circuit.
Claims20
An apparatus, comprising:
- a wireless device having a radio frequency (RF) circuit;
- an omni-directional antenna coupled to the RF circuit;
- a directional antenna coupled to the RF circuit;
- and
- a switch configured to couple at least one of the omni-directional antenna and the directional antenna to an output of the RF circuit.
2 more elements
A method, comprising:
- locating a wireless device having a radio frequency (RF) circuit in a particular location;
- determining whether the wireless device is located in a vicinity of a metal;
- and
- operating the wireless device in a directional mode when the wireless device is located in the presence of metal.
1 more element
An apparatus, comprising:
- a wireless device having a radio frequency (RF) circuit and a metal sensor;
- a first antenna coupled to the RF circuit;
- a second antenna coupled to the RF circuit;
- and
- a controller coupled to the RF circuit, the first antenna and the second antenna, the controller configured to select any of the first antenna and the second antenna responsive to a signal from the metal sensor.
2 more elements
An apparatus, comprising:
- a wireless device having a radio frequency (RF) circuit;
- an omni-directional antenna coupled to the RF circuit, the omni-directional antenna comprising a dipole structure having a first dipole element and a second dipole element;
- a directional antenna coupled to the RF circuit, the directional antenna comprising a patch antenna;
- and
- a ground plane associated with the RF circuit, the ground plane arranged so as to create a slot mode associated with the first dipole element and the second dipole element,
- the first dipole element and the second dipole element generating a first polarization of an electric field in a first axis that is parallel to the orientation of the first dipole element and the second dipole element,
- the slot mode causing the omni-directional antenna to generate a second polarization of the electric field in a second axis that is orthogonal to the first axis.
