Embodiment Construction

[0028] Hereinafter, the present invention will be described based on a configuration example of a resonance element. figure 2 is a partially expanded view of the resonant element. This resonance element includes a stripline resonator, and is used as a filter for high-frequency, wide-band UWB (Ultra Wide Band) communication.

[0029] This resonance element includes a dielectric substrate 2 in the shape of a small cuboid. The dielectric substrate 2 is made of a ceramic dielectric such as titanium oxide, has a dielectric constant of approximately 110, a substrate thickness of 500 μm, a lateral dimension of approximately 3.2 mm in the figure, and a short-side dimension of the main surface of approximately 2.5 mm.

[0030] In addition, the composition and dimensions of the dielectric substrate 2 can be appropriately set in consideration of frequency characteristics and the like.

[0031] figure 2 The rear main surface 2A of the dielectric substrate 2 shown in (A) is the mounti...

Abstract

The present invention provides a resonance element and a method for manufacturing the same. A pallet (50) having a plurality of holding holes (51) is provided with a plurality of flat-board-like filter elements (1) wherein a rear main surface electrode pattern including a ground electrode is arranged on the rear main surface and a front main surface electrode pattern including a main surface electrode is arranged on the front main surface. On a printing surface (53) of the pallet (50), a side surface (2C) or a side surface (2D) of the filter element (1) is arranged. With respect to the side surface arranged on the printing surface (53) of the pallet (50), a side surface electrode pattern having a shape point symmetric within the side surface is formed. Then, the filter element (1) is vertically inverted, and a side surface electrode pattern having the same shape as that of the side surface electrode pattern is formed on a side surface facing the side surface to which the printing is performed. Therefore, the invention may simplify process and reduce costs.

Description

technical field [0001] The present invention relates to a resonator element in which a stripline 1 / 4 wavelength resonator is provided on a dielectric substrate and a method of manufacturing the same. Background technique [0002] A stripline resonator, that is, a resonant element such as a filter or an equalizer provided on a dielectric substrate is used (for example, refer to Patent Document 1). [0003] Here, the configuration of a conventional resonance element will be described using a filter as an example. figure 1 is an expanded view of the previous filter. [0004] The resonance element 101 is configured by interdigitating coupling of five stripline resonators each functioning as a 1 / 4 wavelength resonator. On the back principal surface 102A of the dielectric substrate 102, a ground electrode 103 and terminal electrodes 104A, 104B are provided. On the front main surface 102B, main surface electrodes 105A to 105E are provided. On side surface 102C and side surface ...
