Efficiency of transmission is relatively low.
The content of the invention
It is an object of the invention to provide a kind of 5.8GHz microwave rectification antennas of two antenna element, it is intended to solve existing
The rectification efficiency of the RECTIFYING ANTENNA of 5.8GHz frequencies is relatively low, the less efficient problem of the overall transfer that microwave wireless is transmitted electricity.
The present invention is achieved in that a kind of 5.8GHz microwave rectification antennas of two antenna element, two antenna element
5.8GHz microwave rectification antennas include：
Two rectangular microstrip antennas；
Two rectangular microstrip antennas are connected with power divider by wire；
Power divider is integrated and connected with SMA female coaxial connectors by circuit board, SMA females coaxial connector with
SMA male coaxial connectors axle is connected；
SMA male coaxial connectors are integrated in rectification circuit by circuit board.
Further, the rectification circuit is by input low pass filter, match circuit, commutation diode, output filter group
Into.
Further, two rectangular microstrip antennas receive the microwave energy in space, by power divider same-phase
Two beam microwaves are synthesized a branch of；Low-pass Elliptic Filter in rectification circuit prevents higher hamonic wave from passing through, and rectification circuit is by half
Microwave energy is transformed to direct current by ripple rectification, and output filter is made up of λ/4 microstrip line long and the electric capacity of a 100pf, it is allowed to
By preventing fundamental wave and higher hamonic wave, match circuit effect is that rectification circuit is matched into 50 ohm to direct current.
Further, SMA females coaxial connector is 50 ohmages with SMA male coaxial connectors, is shape after connection
Into a 5.8GHz microwave rectification aerial array.
Further, the rectangular microstrip antenna uses ROGERS series of high-frequency special-purpose boards RO4350B.
Further, the rectangular microstrip antenna is presented mode and is fed using micro-strip line side.
The 5.8GHz microwave rectification antennas of two antenna elements that the present invention is provided, improve 5.8GHz microwave receivings rectification day
Line efficiency, after tested, the RECTIFYING ANTENNA efficiency is up to 58% when load is for 200 Ω.Use two element antennas and power
Distributor composition aerial array increased antenna receiving area, improve the power output of single RECTIFYING ANTENNA, make reception antenna with
Rectification circuit is easily attached.RECTIFYING ANTENNA for single antenna, it is necessary to each antenna to connect a SMA coaxial fitting whole with one
Current circuit.As long as and one coaxial fitting of the RECTIFYING ANTENNA of two antenna elements is connected, the RECTIFYING ANTENNA relative to single antenna is just needed
Want a coaxial fitting that the area occupied of individual antenna is reduced for connecting, reduce connection complexity.It is same per many SMA
Shaft coupling can all add new insertion loss.If using the RECTIFYING ANTENNA of single antenna, two antennas need to connect two rectifications
Circuit, and the output-parallel of rectification circuit is used, because manufacture craft and its precision problem are it cannot be guaranteed that all rectification circuits
Parameter is identical, therefore different rectification circuit power output can be different, and then power when causing different rectification circuit Parallel opertations
The power that different rectification circuits are individually exported can be less than.If only needing to connect a rectification using the RECTIFYING ANTENNA of two antenna elements
Circuit, ensure that the low-loss of power output, be to improve delivery efficiency for the RECTIFYING ANTENNA of single antenna unit；
The loss of rectification circuit each several part is reduced, 5.8GHz RECTIFYING ANTENNA efficiency is improve.Quadravalence elliptical low-pass ripple of the invention
Insertion loss of the device when frequency is 5.8GHz is only 0.4db, and designed match circuit is only by one section of taper microstrip line and one
Section conventional microstrip line is composed in series, and the insertion loss and reflection loss of match circuit are reduced as far as possible.
