Abstract:
1. A receiving and transmitting device for wireless transceivers comprising a grounding portion, a radiating portion, a parasitic element, a first feed body, and a second feed body, all arranged at a substrate; wherein the grounding portion is on one surface of the substrate; the radiating portion having a vertical extension segment extended from top of the grounding portion, a first horizontal extension segment and a second horizontal extension segment respectively extended from one end of the vertical extension segment away from the grounding portion and toward opposite directions, a first radiation segment and a second radiation segment respectively extended from one end of the first horizontal extension segment away from the vertical extension segment and one end of the second horizontal extension segment away from the vertical extension segment; there is a first spacing distance between the first radiation segment and the grounding portion while a second spacing distance is between the second radiation segment and the grounding portion; the parasitic element having an upward opening is arranged over the radiating portion and there is a first coupling gap formed between the parasitic element and the radiating portion while a second coupling gap is formed on the opening; the first feed body is arranged in an area surrounded by the vertical extension segment, the first horizontal extension segment, the first radiation segment and the grounding portion, with a gap therebetween while a first feed point for feeding signals is disposed between the first feed body and the grounding portion; the second feed body is disposed in an area surrounded by the vertical extension segment, the second horizontal extension segment, the second radiation segment and the grounding portion, with a gap therebetween while a second feed point for feeding signals is disposed between the second feed body and the grounding portion.
