Embodiment Construction

[0066] The present invention will be further described below with reference to the drawings and reference numerals.

[0067] As shown in Fig. 8, the phase of the radiating element is adjusted by changing the electrical lengths of the long and short sides of the grid other than the dotted line. The phase of the feeding element and the radiating element can also be compensated using a phase adjuster or amplifier. For example, inserting amplifiers can compensate for phase and amplitude. An inductor, capacitor or resonator can be considered a passive phase adjuster. In addition to using discrete chip inductors, capacitors or resonators, other integrated components may also be preferred. Picture 9 It is an integrated sensor used in the single-layer grid array antenna 900. The antenna 900 includes a grid 902 composed of a short side 904 and a long side 912. One or more short sides 904 are radiating elements. One or more radiating elements 904 contain integrated sensors 906 or 908. ...

Abstract

A grid array antenna configured to operate with millimeter wavelength signals, the grid array antenna comprising a plurality of mesh elements and at least one radiation element; each mesh element comprising at least one long side and at least one short side operatively connected to the at least one long side; at least one of: the at least one radiating element, the at least one short side, and the at least one long side having compensation for improved antenna output for improved antenna radiation.

Description

Technical field [0001] The invention relates to a grid array antenna and its integrated structure, in particular to a grid array antenna and its integrated structure suitable for millimeter wavelength signals. Background technique [0002] The concept of grid array antenna was first proposed by Kraus in 1964, and there have been many studies on grid array antennas afterwards but they have focused on relatively low microwave frequencies. Figure 1 is the basic arrangement of the grid of the grid array antenna, which is composed of a rectangular grid of microstrip lines arranged on a dielectric substrate. The other side of the dielectric substrate is supported by a metal ground layer and is grounded by a metal through hole. Feed through the holes on the layer. Depending on the electrical length of each side of the grid, the grid array antenna can be resonant or non-resonant. [0003] For the resonant grid array antenna, the side length of the grid on the dielectric substrate is the ...
