Novel three-frequency-band three-dimensional patch antenna

Abstract

The invention provides a novel three-frequency-band three-dimensional patch antenna. The novel three-frequency-band three-dimensional patch antenna comprises a dielectric substrate which is formed by two layers of dielectric substrates, an antenna radiation main body and a power divider; the antenna radiation main body which is arranged on the surface of the dielectric substrate is a printed circuit on an upper surface of the upper layer of a dielectric slab; the power divider is arranged between the two layers of dielectric slabs; a feeding point of the antenna radiation main body is connected with the power divider through a via hole in the upper layer dielectric slab of the two layers of dielectric slabs; the dielectric substrate is connected by the first substrate which is unfolded on a first side and a second substrate which is unfolded on the second side to form into a three-dimensional shape having space angles. According to the novel three-frequency-band three-dimensional patch antenna, a first antenna and a second antenna are printed on the circuit board, a certain space angle is formed between the two substrates, and accordingly space is saved, the feeding point is led out through microstrip line to be used for being integrated on a plate with other circuit boards, and integration is achieved.

Description

technical field [0001] The invention relates to an antenna, in particular to a three-band three-dimensional patch antenna. Background technique [0002] With the rapid development of modern wireless communication technology, mobile products have become the mainstream of technology products at this stage, including mobile phones, notebook computers, routers, etc. These products usually work in multiple frequency bands (such as GSM 900MHz, WLAN 2.45GHz, WiMAX and WLAN 5.8GHz, etc.), which requires that the corresponding antennas can also work in multiple frequency bands. [0003] The radiating body of the traditional patch antenna is usually on the rectangular patch through certain techniques (such as slotting, adding new resonance branches, using high-order resonance, etc.) to increase the resonant frequency band of the antenna and realize the multi-frequency of the antenna, but The introduction of these technologies increases the size of the antenna and occupies a large thr...

[0003] The radiating body of the traditional patch antenna is usually on the rectangular patch through certain techniques (such as slotting, adding new resonance branches, using high-order resonance, etc.) to increase the resonant frequency band of the antenna and realize the multi-frequency of the antenna, but The introduction of these technologies increases the size of the antenna and occupies a large three-dimensional space, which is not conducive to the miniaturization of the antenna.
