Problems solved by technology

However, in the high frequency band, such as the millimeter wave frequency band, the redundant branch can also be regarded as a resonant unit, which is likely to cause unwanted radiation and affect the pattern
However, the matching network constructed by lumped parameter components either has no devices corresponding to the frequency band, or has a narrow bandwidth and is too sensitive to the frequency band, resulting in poor matching performance.
[0003] In the prior art, there is a method of directly slotting the patch antenna unit itself to match it. However, due to the limitation of the geometric size of the patch itself in the millimeter wave frequency band, in order to achieve the required slot length, it is usually necessary to bend the slotted wiring , which will result in various parasitic capacitances between the bent traces, such as Figure 9 C1, C2, and C3 shown in , which lead to the excessive value of the single capacitive component in the antenna matching process, resulting in mismatch and difficult adjustment to a satisfactory matching result

Abstract

The invention discloses an antenna patch, patch antenna, antenna array and electronic equipment, wherein the antenna patch includes a patch body, and an opening is arranged inside the patch body; At least one first conductor is provided, and each first conductor is provided with at least one slot that divides the first conductor into two or more sections; the slots of adjacent first conductors are not on the same horizontal line. The patch antenna of the present invention improves the matching degree, reduces loss, and directly adjusts the geometric size of the antenna radiation unit without additionally setting a matching branch or a matching circuit.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an antenna patch, a patch antenna, an antenna array and an electronic device. Background technique [0002] The matching of microstrip patch antennas is usually done by using open or short-circuit branches at the feeder end, or designing a matching network with lumped parameters in the feeder circuit. However, in the high frequency band, such as the millimeter wave frequency band, the extra branch can also be regarded as a resonant unit, which is easy to cause unwanted radiation and affect the pattern. The matching network constructed by lumped parameter components either has no device corresponding to the frequency band, or the bandwidth is very narrow and is too sensitive to the frequency band, resulting in poor matching performance. [0003] In the prior art, there is a way of directly slotting the patch antenna unit itself to match. However, in the millimeter wave freque...
