Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a device for measuring dielectric materials of high dielectric constant ceramic capacitors. Background Art

[0002] The development trend of modern electronic devices is miniaturization, integration and diversification. This trend requires electronic components to be small in size, high in dielectric constant, low in loss and high in stability. The performance of high dielectric constant capacitors can meet the requirements of modern mobile communication equipment.

[0003] Chinese Patent Authorization Announcement No. CN113433392B discloses a device and method for measuring the electromagnetic parameters of dielectric materials.

A transmitting horn is provided on one of the carrier plates, and a corresponding receiving horn is provided on the other carrier plate. The dielectric material to be measured on the carrier plate is clamped between the horn mouth end faces of the transmitting horn and the receiving horn. The present invention optimizes the curve profile of the transmitting horn / receiving horn so that its return loss, cross-polarization, and aperture field distribution meet certain conditions, thereby enabling the device to measure dielectric materials. The signal beam does not need to pass through a period of free space before it is incident on the surface of the dielectric material to be measured, thus avoiding external signal interference and signal diffraction at the edge of the dielectric material, effectively improving measurement accuracy.

There is room for improvement in this regard. Therefore, it is necessary to design a high dielectric constant ceramic capacitor dielectric material measuring device to solve the above problem.
