Abstract

The horn antenna includes printing circuit board (PCB) with control circuit and other parts being setup on it, horn antenna in microstrip type prepared on a side of PCB, and metal microstrip wire as feed in transmission wire of electric wave signal prepared in other side of the PCB. Horn shaped opening is at one end of the antenna. Two edges of the opening form an included angle, and a strip shaped opening is connected to base of the included angle. One end of the metal microstrip wire is connected to control circuit on a side of PCB, and other end is extended to an edge side of the strip shaped opening. Moreover, the microstrip wire turned 90 degrees passes across the strip shaped opening, and turned 90 deg again is extended to another edge side of the strip shaped opening.

Description

technical field [0001] The present invention relates to a kind of microstrip antenna, more specifically, relate to a kind of dual-frequency microstrip antenna that utilizes the fabrication technology of printed circuit to form, and this dual-frequency microstrip antenna is horn shape (in the following description of the present invention , which is called the horn antenna), so that both the high and low frequency bands have sufficient effective bandwidth to effectively improve the system performance of wireless electronic products equipped with the dual-frequency microstrip antenna. Background technique [0002] In recent years, due to the great increase in the market demand for mobile communication products, the development of wireless local area network (WLAN) has been accelerated. Among the standards of many wireless local area networks, the most eye-catching ones are the IEEE802.11 wireless local area network protocol, the IEEE 802.11 protocol Established in 1997, this a...
