Description
Technical Field
The invention relates to the field of spotlight antenna equipment, in particular to a spotlight antenna.
Background
Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all rely on antennas to work when information is transmitted by electromagnetic waves. An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. In addition, in terms of energy transfer with electromagnetic waves, an antenna is also required for energy radiation other than signals. The common antennas are reversible, i.e. the same pair of antennas can be used as both a transmitting antenna and a receiving antenna. The same antenna is the same as the basic characteristic parameters of transmission or reception. This is the reciprocal theorem of antennas. The element is a part of an antenna, a half-wave element is simply a conductor made in the size of half a wavelength of a radio wave, and only when the length of the receiving conductor reaches half a wavelength, a current can be generated in the conductor, so that an electric signal is transmitted from the antenna to the feeder line. The more half-wave vibrators are present in the antenna, the stronger the gain, which is generally expressed in dBi/dBd, the half-wave vibrators: while dipoles are classical, so far the most widely used antennas, single half-wave dipoles can be used simply and individually or as feeds for parabolic antennas, or multiple half-wave dipoles can be used to form an antenna array. The vibrators with equal arm lengths are called dipoles. Each arm has a length of one quarter wavelength and a full length of one half wavelength, and is called a half-wave dipole. The antennas all have a corresponding operating frequency, which may also be considered as a resonant frequency. The basic function of an antenna is energy conversion and directional radiation, and the electrical parameter of the antenna is the ability to quantitatively characterize the energy conversion and directional radiation. The electric parameters of the antenna mainly comprise a directional diagram, a main lobe width, side lobe levels, a directional coefficient, antenna efficiency, polarization characteristics, a frequency band width, input impedance and the like.
The communication antenna generally comprises a radiating oscillator, a reflecting plate, an antenna housing and a feed network. The antenna plastic housing is an indispensable part of the antenna, is generally made of nonmetallic materials, and aims to protect parts in the antenna from the influence of external environment, and has the functions of water resistance, dust resistance and oxidation resistance. The reflecting plate is also an indispensable part of the antenna, is generally made of aluminum plate materials, and aims to play a role in reflection so as to realize the directional radiation performance of the antenna. The antenna plastic housing and the reflecting plate are respectively manufactured by different processing technologies, and are respectively used as two parts of the antenna and are connected together by means of screw fastening and the like. The radiating element is generally made of metal with better conductivity, and has the functions of guiding and amplifying electromagnetic waves, so that the electromagnetic signals received by the antenna are stronger. The half wave vibrator is a conductor made in the size of half wavelength of radio wave, and only the receiving conductor length reaches half wavelength, current can be generated in the conductor, so that the antenna transmits electric signals to the feeder line.
The existing communication antenna is influenced by the antenna design concept, and has the following defects: 1. the boundary of the antenna can influence the radiation performance of the antenna under the constraint of the assembly cost; 2. the radiation performance of the antenna is limited due to the constraint of the size of the antenna; 3. the machined floor boundary is difficult to repair again.
Accordingly, the prior art is still in need of improvement and development.
