Abstract
A radio frequency transmission apparatus includes a first elongated antenna element having a first feed end and a first aperture end. A second elongated element has a second feed end and a second aperture end. The second feed end is coupled to the first feed end. The first and second elongated antenna elements are positioned relative to each other to render a separation between the first antenna element and the second antenna element to increase from the first and second feed ends to the first and second aperture ends. The first and second antenna elements comprise pseudo-conductor material having an electromagnetic constitutive property having a real part greater than the corresponding imaginary part of the electromagnetic constitutive property.
Claims8
A method of configuring an antenna, comprising:
- forming a substantially coplanar configuration of a first elongated antenna element having a first feed end and a first aperture end and a second elongated antenna element having a second feed end and a second aperture end by coupling first and second feed ends such that a separation between the first antenna element and the second antenna element increases from first and second feed ends to first and second aperture ends;
- and
- configuring first and second antenna elements to radiate, upon being excited, emissions that satisfy a predefined antenna performance;
- wherein first and second elongated antenna elements comprise a magnetic pseudo-conductor material having an electromagnetic constitutive property having a real part greater than a corresponding imaginary part of the electromagnetic constitutive property.
A radio frequency (RF) transmission apparatus, comprising:
- a first elongated antenna element having a first feed end and a first aperture end;
- and
- a second elongated antenna element having a second feed end and a second aperture end, the second feed end of the second antenna being coupled to the first feed end, and the first and second elongated antenna elements being position relative to each other to render a separation between the first antenna element and the second antenna element to increase from the first and second feed ends to the first and second aperture ends,
- wherein first and second elongated antenna elements comprise a pseudo conductor material having an electromagnetic constitutive property having a real part greater than a corresponding imaginary part of the electromagnetic constitutive property.
An antenna array configuration for radar imaging applications, comprising:
- a first antenna positioned on a first surface of a support structure, the first antenna being conformable to the first surface;
- and
- a second antenna positioned on a second surface of the support structure, the second antenna being conformable to the second surface;
- wherein the first antenna and the second antenna comprise a magnetic pseudo-conductor having an electromagnetic constitutive property having a real part greater than a corresponding imaginary part of the electromagnetic constitutive property.
