Description

technical field [0001] The invention relates to the field of patch antenna manufacture, in particular to an antenna and a manufacturing method thereof. Background technique [0002] The patch antenna on the surface of the glass substrate can be made by pasting the copper skin, but the echo will be caused if the pasting accuracy is not perfect. In order not to make the pasting process too difficult, technicians need to find a way to adjust the impedance of the patch antenna after the antenna patch is pasted, so that it can still achieve a matching state when there is an error in the paste, reducing the echo and Lower SWR. In the prior art, if the problem of imperfect bonding accuracy is to be overcome, a variable inductance and a variable capacitance are connected between the antenna microstrip line and the ground electrode to achieve the purpose of adjusting the impedance and reducing the standing wave ratio . However, if you want to make a patch antenna with the above me...
