Problems solved by technology

[0005] like figure 1 As shown, due to the different specifications of the antenna and the connector, it is necessary to add a connector (not shown) between the antenna and the filter, which increases the size and cost
At the same time, for the cavity bandpass filter 1', it is usually necessary to add a metal connecting rod low-pass filter 2' to suppress high-frequency harmonics, which increases the size and cost of the filter
Finally, for some situations where the suppression index is relatively strict, the cavity bandpass filter 1' usually has a large number of cavities and a large volume
Therefore, the filter antenna system is limited by the connector, the structure of the metal rod low-pass filter 2' and the number of cavities of the cavity band-pass filter 1', etc., and the integration and miniaturization are greatly limited

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] see figure 2 , the present invention provides an integrated filter system. The integrated filter system includes: a dielectric board assembly 1 ; and a filter circuit 2 arranged on the dielectric board assembly 1 . The filtering circuit 2 includes a low-pass filter 21 and a band-pass filter 22 connected in series.

[0027] The low-pass filter 21 can suppress high-order harmonics, and the band-pass filter 22 realizes a partial out-of-band suppression function. By providing the low-pass filter 21 and the band-pass filter 22 on the same dielectric board assembly 1, integration and miniaturization can be achieved.

[0028] In one embodiment, the dielectric board assembly 1 only includes one dielectric board, and both the low-pass filter 21 and the band-pass filter 22 are disposed on the dielectric board.

[0029] In another embodiment, the die...

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an integrated filter system and an antenna system. Background technique [0002] Antennas and filters are the two most important key components in passive components, and play an important role in wireless communication systems. [0003] The antenna plays the role of transmitting and receiving wireless electromagnetic signals, while the microwave filter plays the role of selecting signals, attenuating noise, filtering mirror frequency interference, etc., and the commonly used cavity filter is used. With the development of wireless communication, there is an increasing need for high-performance portable terminal equipment, which requires the miniaturization and integration of antennas and filters. [0004] At present, antennas and filters are usually independent modules. The traditional filter-antenna system design method focuses on the antenna and filter components ...
