Definitions

  • the present invention relates to an antenna used as a front end of a transmitter and a receiver, in particular to a microstrip array antenna unit.
  • Microstrip antennas as transceiver front-ends, are widely used in satellite communications, radar, weapon fuze and other systems. At present, practical microstrip array antenna units are mostly single patch units. The center frequency of the work is determined by the size of the patch. The working frequency is narrow, the gain is low, and the efficiency is low. Applications are limited.
  • An object of the present invention is to overcome the disadvantages of the foregoing prior art and provide a microstrip array antenna unit with a wide frequency band, high gain, and high efficiency.
  • a wideband microstrip array antenna unit having a microstrip feeder, a dielectric layer, a grounded metal plate, a coupling window opened on the grounded metal plate, a metal patch, and a patch medium
  • the substrate is characterized by having a first patch and its dielectric substrate and a second patch and its dielectric substrate.
  • the hollow metal support and the dielectric pillar are fixedly connected to the ground metal plate in this order.
  • the sheet is fixed on the hollow hole of the metal support, the dielectric substrate of the second patch is fixed on the dielectric pillar, one is formed between the grounded metal plate and the first patch, and the other is formed between the first patch and the second patch. Resonant cavity.
  • the ground metal plate separates the feeder portion from the radiating portion.
  • the input energy on the feeder line can be coupled into the two resonant cavities through the coupling window, and the first and second two-layer patches are excited by the resonant cavity. Get better impedance matching and radiate as much input energy as possible.
  • each unit can share a ground metal plate, and the hollow metal support can also be made of a thick metal plate to form a microstrip array antenna as a whole.
  • FIG. 1 is a schematic diagram of a longitudinal section of an embodiment of the present invention.
  • FIG. 2 is a top view of an embodiment of the present invention.

Abstract

L'invention concerne un élément d'antenne en réseau microbande à large gamme de fréquences comprenant un fil d'amenée microbande, une couche diélectrique, une plaque métallique de mise à la masse, une fenêtre de couplage, une première pièce et son substrat diélectrique et une seconde pièce et son substrat diélectrique. Sur la plaque métallique de mise à la masse un support métallique creux est relié à demeure à des montants diélectriques. Le substrat diélectrique de la première pièce repose de manière fixe dans la cavité du support métallique et le substrat diélectrique de la seconde pièce repose, quant à lui, de manière fixe sur les montants diélectriques. La partie intermédiaire entre la plaque métallique de mise à la masse et la première pièce et entre la première pièce et la seconde pièce forme une cavité résonante. L'invention est caractérisée par sa large gamme de fréquences, son gain élevé, son efficacité, la simplicité de la structure et un montage aisé.
