Abstract

The present invention relates to a wireless LAN antenna and wireless LAN card, which can transmit / receive RF signals in a high frequency band (5 GHz) and a low frequency band (2.4 GHz) required in the wireless LAN. The wireless LAN antenna of the present invention includes a radiation electrode, a matching electrode and a feeding electrode. The radiation electrode has a predetermined area to determine a transmission / reception frequency band of the antenna. The matching electrode has at least one open stub. The feeding electrode has a feeding point formed at an arbitrary position of the feeding electrode to receive a current, with a first end connected to the radiation electrode and a second end connected to the matching electrode. Further, the feeding point and a ground point are arbitrarily set on the feeding electrode, thus adjusting the impedance and frequency of the wireless LAN antenna.

Description

technical field [0001] The present invention mainly relates to an antenna installed in a wireless local area network, and more particularly relates to a wireless local area network antenna and a wireless local area network card thereof, which can operate in a high frequency band (5 GHz) and a low frequency band without increasing the size of the antenna. (2.4GHz) to transmit / receive RF signals and adjust antenna characteristics without changing the antenna structure. Background technique [0002] Recently, with the miniaturization and weight reduction of mobile communication equipment and the multiplexing of one transmission / reception frequency band to two or more frequency bands, the antenna, which is one of the key components for wireless transmission / reception of mobile communication terminals, has been changed from External helical antennas evolved to F or inverted F antennas. [0003] In particular, in the case of a wireless local area network (LAN), a dual-band antenn...
