The radiation characteristic
of the antenna is changed by transforming the overall structure of the antenna according [7, 8].
Broadband planar monopole antennas have received considerable attention due to their attractive advantages, such as ultra-wide frequency band, good radiation characteristic
, simple structures, low cost and easy fabrication [19-21].
But he concurs with Forbes that the infrared detectors "are more sensitive and can do a more thorough job" of searching for radiation characteristic
of recent supernova explosions than radio telescopes.
 and Xia and Yin  studied the radiation characteristic
of plasma antenna through theoretical derivation.
Simulation 2: The radiation characteristic
of the circular metal plate, which has the same radius as the metal ball, are analyzed by means of the simulation modeling method proposed in this paper.
These polar plots at 6 and 18 GHz exhibit the desired symmetric radiation characteristic
required for polarization diverse applications.
Where large amounts of matter happen to be falling into the black hole, friction and gravitational stresses on the infalling matter can generate the radiation characteristic
of a quasar, which far outshines all the rest of the surrounding galaxy.
With the good directional radiation characteristic
of Yagi-Uda antenna, it is a good choice to achieve our bidirectional radiation target.
The proposed antenna has nearly omnidirectional radiation characteristic
in the H-plane and figure-eight radiation pattern in the E-plane over the three bands.
This science of astrochemistry proceeds by examining the spectra of objects in the sky for emissions or absorptions of radiation characteristic
of different chemical substances, either fairly sharp wavelengths (lines) or short ranges of wavelengths (bands).
And at present the conformal array antenna research is mainly concentrated on the conformal antenna unit design and radiation characteristic
analysis, pattern analysis, synthesis, and optimization, as well as the conformal array antenna signal processing and so on; the study of deformation is relatively less.
