Abstract
The present invention is to provide a patch horn antenna of dual frequency formed on a printed circuit board of a wireless electronic product, in which the horn antenna is formed on one side of the print circuit board, a first patch line is formed on the other side of the printed circuit board as a feed transmission line thereof by means of signal wave coupling, and a second patch line being extended from an opening of the horn antenna at one oblique side toward the other oblique side of the opening for effectively controlling the ranges of the frequency bands to obtain a good match between high and low frequency bands via adjusting the size of the second patch line the degree of the angle between two oblique sides of the opening or the coupling area of the first patch line.
Claims9
A patch horn antenna device operable in two different frequency bands comprising:
- a print circuit board including a control circuit of an wireless electronic product and a plurality of components for installation;
- a horn antenna formed on one side of the print circuit board, the horn antenna including a horn opening formed at one side, the opening having an angle formed between two oblique sides thereof, and an elongate recess extended inward from a corner of the angle;
- and
- a first patch line formed on the other side of the print circuit board, the first patch line being served as a feed transmission line of signal wave, the first patch line having one end coupled to the control circuit printed on the other side of the print circuit board and the other end extended substantially parallel with one side of the recess, turned 90 degrees to cross the recess, and turned 90 degrees again to extend substantially parallel with the other side of the recess.
