Description
Technical field
The present invention relates to field of antenna, and in particular to a kind of adaptable antenna.
Background technology
Antenna is a kind of converter, and, the guided wave of transmission above-the-line promotion, it (is typically freely to be transformed into unbounded medium for it
Space) in the electromagnetic wave propagated, or carry out opposite conversion.It is used for launching or receiving the portion of electromagnetic wave in wireless device
Part.The engineering systems such as radio communication, broadcast, TV, radar, navigation, electronic countermeasure, remote sensing, radio astronomy, it is every to utilize electricity
Magnetic wave carrys out transmission information, depends on antenna to be operated.In addition, in terms of energy is transmitted with electromagnetic wave, the energy of non-signal
Amount radiation is also required to antenna.General antenna all has invertibity, i.e., both can be used as transmitting antenna with common antenna, it is also possible to connect
Receive antenna.The same antenna is identical as transmitting or the fundamental characteristics parameter received.Here it is the reciprocal theorem of antenna.
Aerial radiation is radio wave, and reception is also radio wave, but emitter passes through feeder line and is sent into antenna
It is not radio wave, radio wave directly can not be sent into receiver by reception antenna through feeder line, wherein having to pass through energy
Transfer process.In transmitting terminal, brewed high frequency oscillating current (energy) caused by emitter inputs transmitting day through feed equipment
Line (feed equipment can be different with form with frequency, directly transmit current wave or electromagnetic wave), transmitting antenna is by high frequency electric or leads
Ripple (energy) is changed into radio wave-Free Electromagnetic ripple (energy) and radiated to surrounding space (see Fig. 1)；In receiving terminal, radio
Ripple (energy) is transformed into high frequency electric by reception antenna or guided wave (energy) is sent to receiver through feed equipment.From above-mentioned mistake
Journey can be seen that the device that antenna does not still radiate and received radio wave, while be also an energy converter, be circuit with
The interface device in space.
The receiving channel of antenna is excessively single, with decline of the signal in transmitting procedure, can cause signal weaker, improves
Information transfer channel is advantageous to strengthen signal, improves data transfer rate, improves the extensive adaptability of antenna.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of adaptable antenna, the antenna is by setting multiple semicircles
Channel is transmitted, wavelength distance transmission is maintained on antenna so that main beam can be located at any direction that end-fire is mapped to from side, have
The lifting of enhancing and data transfer rate beneficial to signal.
The present invention is achieved through the following technical solutions：
A kind of adaptable antenna, including substrate, substrate upper surface is provided with transmission line structure, the lower surface of substrate
Be provided with earth plate, transmission line structure includes connected multiple semicircular ring transmission lines and linear transmission line, using linear transmission line as
Center, multiple semicircular ring transmission lines are uniformly distributed in the both sides of linear transmission line up and down, and linear transmission line is arranged on transmission knot
The both ends of structure, the end of transmission line structure are connected with matched load.
Semicircular ring transmission line is shifted to install in the both sides up and down of linear transmission line two-by-two.
The diameter of the semicircular ring transmission line of the both sides up and down of linear transmission line is different.
The semicircle of semicircular ring transmission line is centrosymmetric two-by-two is arranged on linear transmission line both sides up and down.
Gap is offered on earth plate.
Gap is annular slot.
The present invention compared with prior art, has the following advantages and advantages：
The present invention maintains wavelength distance transmission so that main beam by setting multiple semicircle transmission channels on antenna
Any direction that end-fire is mapped to from side can be located at, be advantageous to the enhancing of signal and the lifting of data transfer rate.
