Specific implementation mode
Array antenna is the antenna that multiple radiating elements rearrange according to certain rules.Multi-frequency array antenna is by supporting not
The antenna set collectively constituted with multiple array antennas of working frequency range.The size of multi-frequency array antenna is typically by reflecting
What the size of plate determined, and the size of reflecting plate is shared on reflecting plate by all radiating elements in the multi-frequency array antenna
Region size determine.As shown in Figure 1, it is a kind of structural schematic diagram of traditional multi-frequency array antenna, the multifrequency battle array
Array antenna includes air substrate (air substrate is a kind of medium substrate being made of air layer, dielectric constant 1), reflecting plate
101, working frequency range is 2.4 girz (English：Gigahertz) microstrip antenna 102 and working frequency range of frequency range are 5GHz frequency ranges
Microstrip antenna 103.Both microstrip antennas respectively include respective radiating element and respective feeding network, wherein feed
Tie point between network and radiating element is feed mouth.Multiple radiating elements on reflecting plate 101 can pass through insulating support
Frame is air substrate above reflecting plate 101, between this multiple radiating element and reflecting plate 101.The radiation list of microstrip antenna 102
The radiating element of member and microstrip antenna 103 is separately separated arrangement on reflecting plate 101.As seen from Figure 1, microstrip antenna
102 radiating element and the radiating element of microstrip antenna 103 occupy larger region on reflecting plate 101, this causes instead
The size for penetrating plate 101 is larger, thus the size of multi-frequency array antenna is larger.Wherein, microstrip antenna (English：microstrip
Antenna) it is other side setting reflecting plate and the antenna that is formed in medium substrate side patch plus radiating element.Reflecting plate is to lead
Body earth plate (English：ground plane).Medium substrate makes to open a way between radiating element and reflecting plate.Radiating element and reflection
Open circuit between plate generates electromagnetic wave.Radiating element is the basic structural unit of microstrip antenna, it can effectively eradiation or reception
Electromagnetic wave.Working frequency range is the frequency range of microstrip antenna work.Feeding network is the antenna feeder (English of multiple radiating elements
Text：Antenna feed line) constitute circuit network.
