Abstract
An example method of designing a multi-band antenna includes specifying a first portion of the multi-band antenna in a tangible medium, where the first portion corresponds to an existing design of a single-band monopole antenna for operating in a first frequency band, and specifying in the tangible medium a second portion of the multi-band antenna that is added to the first portion, where the second portion includes a dipole parasitic resonator that is resonant in a second frequency band.
Claims15
A multi-band antenna comprising:
- a first portion that corresponds to a monopole antenna operable in a first frequency band, the first portion comprising:
- a first segment connected to a ground plane portion and extending away from the ground plane portion,
- a second segment connected to the first segment and extending away therefrom in a first direction that is approximately parallel to the ground plane portion, and
- a third segment connected to the second segment and extending away therefrom in a second direction that is away from the ground plane portion, a signal source being connected to the third segment;
- and
- a second portion connected to the first portion as a dipole parasitic resonator that is resonant in a second frequency band, the second portion comprising a fourth segment that:
- is connected to the second segment at approximately a longitudinal center of the fourth segment,
- faces the third segment, and
- has a longitudinal axis oriented along a third direction that is approximately perpendicular to the first direction.
A method of forming a multi-band antenna, comprising:
- forming a first portion of the multi-band antenna in a tangible medium, the first portion corresponding to an existing design of a single-band monopole antenna for operating in a first frequency band;
- and
- forming in the tangible medium a second portion of the multi-band antenna that is added to the first portion, the second portion comprising a dipole parasitic resonator that is resonant in a second frequency band.
A method of manufacturing a multi-band antenna, comprising:
- forming a first portion of the multi-band antenna that, upon being formed, is a single-band monopole antenna that is operable in a first frequency band;
- forming a second portion of the multi-band antenna that is separate from the first portion;
- and
- connecting the second portion to the first portion such that the second portion, upon being connected, acts as a dipole parasitic resonator that is resonant in a second frequency band.
