Description
Technical field
The present invention relates to antenna, particularly relate to a kind of bean sprouts shape single-frequency narrow band microstrip antenna.
Background technology
Microstrip antenna is on a thin-medium substrate, and one side encloses thin metal layer as ground plate, and another side photoetching caustic solution makes the metal patch of definite shape, utilizes the antenna that microstrip line or coaxial probe are formed patch.Microstrip antenna divides 2 kinds: 1. patch shape is an elongated strip, be then micro-strip oscillator antenna.2. when paster is a surface elemant, be then microstrip antenna.If ground plate is carved gap, and when the another side of dielectric substrate prints out microstrip line, cutler feed, then form microstrip slot antenna.
Just propose the concept of microstrip antenna as far back as nineteen fifty-three, but do not cause the attention of engineering circles.In the research that the fifties and the sixties only have some fragmentary, real development and use are in the seventies.A conventional class microstrip antenna is on a thin-medium base (as polytetrafluoroethylglass glass fiber pressure layer), one side encloses thin metal layer as ground plate, the methods such as another side photoetching corrosion make the metal patch of definite shape, utilize microstrip line and axis probe to patch, this just constitutes microstrip antenna.When paster is a surface elemant, it is claimed to be microstrip antenna; If paster is an elongated strip, be called microstrip array sub antenna.
