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.
- the broadband microstrip array antenna unit of the present invention has a microstrip feed line 1, a dielectric layer 2, a ground metal plate 3, a coupling window 4 opened on the ground metal plate, and a first metal patch 6.
- a microstrip feed line 1 a dielectric layer 2, a ground metal plate 3, a coupling window 4 opened on the ground metal plate, and a first metal patch 6.
- the second metal patch 8 and its dielectric substrate 9, the hollow metal support 13 and the dielectric pillar 12 are fixedly connected in order on the ground metal plate 3, and the dielectric substrate 7 of the first patch 6 passes through
- the screw 10 is fixed on the edge step 11 of the hollow hole of the metal support 13, and the dielectric substrate 9 of the second patch 8 is fixed on the dielectric pillar 12. Therefore, between the ground metal plate 3 and the first patch 6, the first A resonant cavity 51, 52 is formed between each of the patch 6 and the second patch 8.
- the area of the first metal patch 6 is smaller than the cross section of the resonant cavity 51 where the first metal patch 6 is located, so that the resonant cavity 51 can excite the first and second metal patches.
- the cross section of the two resonant cavities can be square, rectangular, or circular, and the shape of the two metal patches corresponds to the cross sectional shape of the resonant cavity.
