Embodiment 1

[0040] The present invention provides a millimeter-wave phased array antenna array integrated conversion connector, including a metal ground 2, a terminal 1 arranged on the front of the metal ground 2, and a metal pin 3 arranged on the back of the metal ground 2, and the terminal 1 and the metal pin 3 are one A corresponding connection forms an inner conductor, and the terminal 1 adopts an elastic structure, such as an elastic stretchable fur button. The metal ground 2 is an outer conductor and the terminals 1 on the front of the metal ground 2 or the metal pins 3 on the back are arranged in an array, and the terminals 1 on the front of the metal ground 2 or the metal pins 3 on the back are preferably arranged in a 4*4 array. An impedance medium is filled between the inner conductor and the outer conductor and matched to 50 ohms. The impedance medium is preferably made of Teflon.

[0041] The distance between two adjacent terminals 1 or two adjacent metal needles 3 is half the...

Embodiment 2

[0045] This embodiment is a preferred example of Embodiment 1.

[0046] In this example, if figure 1 , figure 2 , image 3 As shown, the integrated conversion joint 7 includes 16 positive elastic terminals 1, metal ground 2, and 16 reverse metal pins 3, wherein the front terminal 1 and the reverse metal pin 3 are interconnected, and the millimeter wave signal is connected between the terminal 1 and the metal pin 3 transfer between.

[0047] The terminals 1 and the metal pins 3 are arranged in a 4*4 array, and the arrangement spacing is 1 / 2 of the working wavelength, and the specific size is determined by the working center frequency. The diameter of the terminal 1 is 0.4mm, and the stretchable elastic range is 0-0.4mm. The diameter of the metal pin 3 is also 0.4mm, and the length is 1mm.

[0048] Terminal 1 and metal pin 3 are the inner conductor of the adapter, and metal ground 2 is the outer conductor of the adapter. The space between the inner conductor and the outer c...

Abstract

The invention provides a millimeter wave phased-array antenna array integration adapter which comprises a metal ground, terminals arranged on the front face of the metal ground and metal needles arranged on the back face of the metal ground, and the terminals and the metal needles are connected in a one-to-one correspondence mode to form inner conductors. The metal ground is an outer conductor, terminals on the front face of the metal ground or metal needles on the back face of the metal ground are arranged in an array when the metal ground overlooks down, and impedance media are filled between the inner conductor and the outer conductor. The use number of common radio frequency connectors is greatly reduced, and the manufacturing cost of the phased-array antenna array is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a millimeter-wave phased array antenna array integration adapter. Background technique [0002] Millimeter-wave phased array antennas are gradually used in mobile communication systems. Due to their high operating frequency and large array size, millimeter-wave phased array antennas are small in size and high in manufacturing costs. The phased array antenna based on microstrip line technology is widely used in beamforming communication systems because of its flat structure, small size, easy processing, and low cost. [0003] For the interconnection between microstrip line antenna array and multi-channel RF transceiver components, the traditional method is to use multi-level RF connectors in series, that is, the antenna array and transceiver components are respectively installed with SMP connectors and interconnected through K-K connectors. This method requires thre...
