Abstract
Ultra-wide band (UWB) Frasera antenna elements are disclosed, including a radiator and fencing structure having features that designed to obtain 3GPP Standards-compliant levels of performance over a 45% bandwidth for return loss, polarization discrimination, polarization isolation, and mutual coupling.
Claims21
An ultra-wide band (UWB) Frasera antenna element the UWB antenna element comprising:
- a radiator configured to provide a first polarization and a second polarization;
- and
- a fencing structure forming a perimeter around the radiator the fencing structure including two first parallel fences having a first fence height and two second parallel fences orthogonal to the two first parallel fences and having a second fence height, the two first parallel fences and the two second parallel fences forming a gap at each of four corners of the fencing structure, each of the two first parallel fences having two first outer slants each first outer slant being configured to slope toward a corner from the first fence height to a corner height and each of the two second parallel fences having two second outer slants, each second outer slant being configured to slope toward the corner of the four corners from the second fence height to the corner height the corner height being less than the first fence height and less than the second fence height, each of the two first parallel fences having a third fence height at a first center of the two first parallel fences, the third fence height being less than the first fence height the two second parallel fences having a fourth fence height at a second center of the two second parallel fences, the fourth fence height being less than the second fence height.
An ultra-wide band, UWB, Frasera antenna element, the UWB Frasera antenna element comprising:
- a radiator and a fencing structure forming a perimeter around the radiator
- the radiator having a first pair of two oppositely directed petals and a second pair of two oppositely directed petals the first pair of oppositely directed petals being orthogonal to the second pair of oppositely directed petals each petal extending from a center region of the radiator toward one of four corners of the fencing structure;
- and
- the fencing structure having a first pair of two oppositely facing fences and a second pair of two oppositely facing fences, each oppositely facing fence being on a different side of the radiator, the two pairs of oppositely facing fences being configured to form the four corners of the fencing structure each fence of a first pair of oppositely facing fences having a first center, a first fence height, first outer slants and first inner slants, each fence of a second pair of oppositely facing fences having a second center, a second fence height, second outer slants and second inner slants, a first outer slant extending from the first fence height to a corner height at a first corner, a second outer slant extending from the second fence height to the corner height at the first corner, a first inner slant extending from the first fence height to a third fence height at the first center, and a second inner slant extending from the second fence height to a fourth fence height at the second center.
