Description
Technical field
The present invention relates to antenna, more particularly to a kind of transmitting-receiving of packaged lens feed to collect ellipsoid lens antenna in pairs.
Background technology
A series of research is carried out to lens antenna system very early in the world, traditional lens antenna is typically using flat
The geometries such as face, sphere, hyperboloid, parabola, but these method scanning ranges are limited, loss is big, working band is narrow, no
The requirement of modern millimeter-wave systems application can be met.The seminar that the Prof.G.M.Rebeiz of University of Michigan is led is earliest
Research field (D.F.Filipovic, S.S.Gearhart the and G.M.Rebeiz, " Double- of di-lens are started
slot antennas on extended hemispherical and elliptical silicon dielectric
lenses,”IEEE Trans Microwave Theory Tech.,MTT-41,pp.1738-1749,Oct.1993).He
A kind of dielectric lens antenna particularly suitable for millimere-wave band work is proposed within 1994, it is prolonged by a hemisphere and one section of cylindricality
Long section composition, its feed antennas very simply can be integrated on the focal plane of lens.The length for adjusting cylindricality extension can be with
The focal length of lens is finely tuned, when simple beam is applied, the general length for adjusting cylindricality extension causes the gain of antenna to reach
Highest.And when multi-beam is applied, then require make it that the flatness of each wave beam is optimal, with simple beam application
Compare, at this time the gain of each scanning beam have general 2~3dB decline (D.F.Filipovic, G.P.Gauthier,
S.Raman and G.M.Rebeiz,“Off-axis properties of silicon and quartz dielectric
lens antennas,”IEEE Trans.Antennas and Propagation,AP-45,No.5,pp.760-766,May
1997)。
In the case where high-gain is applied, weight can greatly increase above-mentioned dielectric lens antenna, be brought to practical application huge
It is big difficult, double ellipsoid lens antenna systems at this moment can be used, this antenna system is divided into feed antenna and double ellipsoid lens
Two parts form, and when the phase center of feed antenna overlaps with the focus of double ellipsoid lens, are radiated and produced by feed antenna
Electromagnetic wave will be changed into parallel beam by double ellipsoid lens and radiate, therefore can easily realize high-gain (X.Wu,
G.V.Eleftheriades and T.E.van Deventer,“Design and characterization of single
and multiple beam mm-wave circularly polarized substrate lens antennas for
wireless communications,”IEEE Trans.Microwave Theory Tech.,MTT-49,pp.431-441,
March 2001)。
However, the azimuth plane of globe lens antenna is identical with pitching face beam angle, if necessary to adjust beam angle, the two
It can change simultaneously, it is impossible to meet azimuth plane and pitching face realize different coverages the needs of.The focus of double ellipsoid lens
Only one, the gain highest when the phase center of feed antenna overlaps with the focus of double ellipsoid lens, existing double ellipsoids
Lens antenna other not focal beam gains in face are lower than the beam gain of focal point, cause in multi-beam application scenarios
Under, scanning angle is bigger, and gain is lower, and secondary lobe is higher, and beam angle is wider.This globe lens defocusing wave beam performance compared with
Difference, difficulty can be brought in actual applications.
