Abstract
An antenna assembly includes a first antenna fastened to a first member disposed in a second member, where the first member is spaced apart from the second member in a radial direction. The antenna assembly includes a second antenna fastened to the second member. A direction of an antenna moment associated with the first antenna or the second antenna intersects an axial direction of the first member, an axial direction of the second member, or both.
Claims20
An antenna assembly comprising:
- a first antenna fastened to a first member disposed in a second member, wherein the first member is spaced apart from the second member in a radial direction;
- and
- a second antenna fastened to the second member,
- wherein:
- the first antenna comprises one or more first antenna segments each partially wrapping around the first member, without fully wrapping around the first member,
- the second antenna comprises one or more second antenna segments each partially wrapping around the second member, without fully wrapping around the second member,
- a direction of an antenna moment associated with the first antenna intersects an axial direction of the first member, an axial direction of the second member, or both;
- and
- a direction of an antenna moment associated with the second antenna intersects the axial direction of the first member, the axial direction of the second member, or both.

An antenna comprising:
- one or more antenna segments each partially wrapped around and releasably fastened to a member disposed in a borehole, without fully wrapping around the member, wherein:
- the member surrounds a second member disposed in the borehole and is spaced apart from the second member in a radial direction,
- a direction of an antenna moment associated with the one or more antenna segments intersects an axial direction of the member, an axial direction of the second member, or both, and
- the antenna is configured to at least one of:
- wirelessly receive power from a second antenna which is fastened to the second member and provide data signals representative of measurement data to the second antenna, or
- wirelessly transmit second power to the second antenna and receive data signals representative of second measurement data from the second antenna.
