Embodiment Construction

[0032] The structure of the dual-frequency inverted-F antenna of the present invention is simple, and it is different from the traditional inverted-F antenna in which the radiating metal sheet is placed above the ground plane and the ground plane is short-circuited. The dual-frequency inverted-F antenna of the present invention uses the radiation metal sheet or The wiring and the ground plane are directly printed on the circuit substrate, which can improve the convenience of manufacture.

[0033] Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 1 is a structural top view of a dual-frequency inverted-F antenna according to an embodiment of the present invention. Fig. 2 is a side view of Fig. 1 viewed along the X direction. In FIG. 1 , a metal line 40 , a metal line 42 are printed on the first surface 12 of the substrate 10 , and a 50-ohm microstrip feeder that provides signals to the metal line 40 and the metal line 42 through the feed-in point 62 and the feed-in point ...

Abstract

The dual-band inverted-F antenna at least includes base plate with opposite first surface and second surface, first radiation microband wire formed on first surface of base plate, second radiation microband wire formed on first surface of base plate, feeder formed on first surface of base plate, said feeder is connected between first microband wire and second microband wire for feeding signal, connecting wire for simulataneously connecting with first microband wire and second microband wire and common metal short circuit rod for making first microband wire and second microband wire form shortcircuit and connect with ground.

Description

technical field [0001] The present invention relates to a dual-band Inverted-F antenna, in particular to an Inverted-F printed antenna (Printed Antenna) that can operate in dual-bands and is used in a circuit substrate. Background technique [0002] With the improvement of communication technology, the application of communication technology in scientific and technological products is increasing day by day, making the related communication products more and more diversified, and in recent years, consumers have higher and higher requirements for the functions of communication products, so many of them have different designs and Functional communication products are constantly being proposed, such as the integrated design of dual-frequency and triple-frequency communication products, and even the application of multi-frequency bands are recent popular trends, coupled with the increasingly mature integrated circuit technology, making the product The volume also gradually tends ...
