Embodiment Construction

[0016] Most of the area of ​​the passive components in the wireless communication module is usually occupied by the antenna, so it has become a demand to minimize the size of the antenna and maximize the efficiency within the limited area of ​​the wireless device. Compared with other antenna types, monopole antennas occupy a very small area, especially when formed into folded, spiral or meander shapes. A matching network (also called a matching circuit) that matches the antenna impedance of a drive / receive circuit to the antenna is connected to the antenna. The matching network uses a substrate area of ​​passive components. In addition, the gain value and bandwidth of the monopole antenna are fixed values.

[0017] figure 1 An antenna 100 according to an embodiment of the present invention includes a perspective view of an antenna conductor 105 having a slot. The antenna 100 minimizes the substrate area used, does not include matching passive components, and has adjustable ...

Abstract

The present invention discloses a manufacturing method of an antenna. The antenna comprises a signal feeding-in structure, an antenna conductor and a shielding part. The antenna conductor is coupled with the signal feeding-in structure. Furthermore the antenna conductor is internally provided with a notch. The shielding part capacitively shields one mechanical opening end of the notch.

Description

technical field [0001] The present invention relates to an antenna, and in particular to an antenna for wireless transmission and / or reception of radio signals. Background technique [0002] Antennas for wireless transceivers need to be light, thin, short, and small. In order to enable mass production and reduce costs, antenna design has changed from non-planar antennas such as Planar Inverted-F Antennas (PIFA) for mobile phones to planar PCB antennas such as monopole antennas. In addition, chip antennas have been commonly used in small handheld wireless devices. However, compared to PCB antennas, chip antennas still have efficiency and area issues. Contents of the invention [0003] The present invention provides an antenna for wireless transmission and / or reception of radio signals, and the present invention provides one or more embodiments related to the antenna for wireless transmission and / or reception of radio signals. [0004] The invention provides an antenna, w...
