Abstract
The utility model discloses a kind of square patch antenna, this circuit structure is by λ/2 ripple microstrip line, and the realizations such as substrate, this antenna only has a port.The utility model can be widely used among mobile radio system; Its structure is simple, volume is little, easy to use, superior performance, is easy to the integrated of circuit.
Description
Technical field
The utility model belongs to antenna, particularly a kind of square patch antenna, belongs to electronics and communication field.
Background technology
In the last few years, a series of research about antenna had been carried out both at home and abroad.In specific frequency range, achieve many achievements, be especially used in WCDMA technology.Antenna has important effect in the systems such as microwave communication, electronic countermeasures, microwave measurement, phased array radar assembly.As in the base station and mobile system of mobile communication, the common apparatus that antenna is connected with antenna as sending and receiving circuit; Improve the object of the stability of a system and reliability.
And traditional antenna is due to the problem of its circuit structure, make temperature sensitivity extremely strong, applicability is very limited.The utility model, for above problem, can effectively solve, and to meet system requirements, and stability is high, volume is little, processing is simple, applied widely.
Summary of the invention
The utility model object is to provide the microstrip antenna that a kind of square patch antenna, structure are simple, volume is little, stability is high, temperature sensitivity is relatively little.
The technical scheme realizing the utility model object is: realized by λ/2 ripple microstrip line and substrate; Port connects 50 ohmages.Each device equal λ/2 ripple microstrip line realizes.Resistance in its equivalent circuit structure can adopt negative resistance to realize, and can realize the transmission of signal in 1GHz-10GHz frequency range.
Compared with prior art, because the utility model adopts microstrip line to process, the remarkable advantage brought is: (1) signal attenuation is less; (2) small volume; (3) out-of-band noise suppresses good; (4) good stability; (5) temperature-insensitive is strong; Be applicable in the various mobile communication system higher to performance requirement.
Accompanying drawing explanation
Fig. 1 is a kind of square patch antenna structure chart of the utility model.
Fig. 2 is a kind of square patch antenna equivalent circuit diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Composition graphs 1, the utility model is a kind of lamped element antenna, and the example choosing an objective wave band is described in detail, and comprises a kind of square patch antenna, structure is simple, volume is little, stability is high, microstrip antenna that temperature sensitivity is relatively little.
Wherein square patch is realized by λ/2 ripple microstrip line, and its length is L, and wide is W; Substrate is that ε material serves as a contrast realization by dielectric constant; Its thickness is h; Port one connects 50 ohmages.As shown in Figure 2, resistance R wherein, R1 adopt negative resistance to realize to its equivalent circuit structure, can realize the transmission of signal in 1GHz-10GHz frequency range.
This invention design performance is good, can meet the requirement of system.
A kind of square patch antenna of the utility model, composition graphs 1, Fig. 2, its operation principle is summarized as follows: comprise a kind of square patch antenna, structure is simple, volume is little, stability is high, microstrip antenna that temperature sensitivity is relatively little.
Wherein square patch is realized by λ/2 ripple microstrip line, and its length is L, and wide is W; Substrate is that ε material serves as a contrast realization by dielectric constant; Its thickness is h; Port one connects 50 ohmages.As shown in Figure 2, resistance R wherein, R1 adopt negative resistance to realize to its equivalent circuit structure, can realize the transmission of signal in 1GHz-10GHz frequency range.This invention design performance is good, can meet the requirement of system.Thus realize the transmission effect of signal.
Being made up of λ/2 ripple microstrip line in the utility model patch antennas, processes simple, functional, can to meet system requirements.
