Claim Text:
1. A high isolation electromagnetic transmitter and receiver comprising: a grounding portion, a first antenna body extended from the grounding portion, a second antenna body extended from the grounding portion, an isolation portion that is extended from the grounding portion and located between the first antenna body and the second antenna body; and a parasitic element that is corresponding to the isolation portion and disposed between the first antenna body and the second antenna body; wherein the isolation portion includes a vertical extension segment extended upward from the grounding portion; one end of the vertical extension segment away from the grounding portion is extended toward two opposite directions to form a first horizontal extension segment and a second horizontal extension segment; the isolation portion is T-shaped; the first antenna body is extended from the grounding portion; the second antenna body is extended from the grounding portion; the parasitic element is reverse T-shaped and arranged over the grounding portion so as to isolate the first antenna body and the second antenna body; wherein the first antenna body includes a first short circuit segment extended from the grounding portion, a first feed point for feeding signals arranged adjacent to the grounding portion and separated from the first short circuit segment, a first vertical segment formed by the upward extension of the first short circuit segment, a first horizontal segment formed by horizontal extension of an outer end of the first vertical segment, a first branched vertical segment formed by extension of the first horizontal segment toward the grounding portion, a first rear-end segment formed by extension of the first branched vertical segment toward the first vertical segments, and a first feed segment extended horizontally between the first short circuit segment and the first feed point; the second antenna body includes a second short circuit segment extended from the grounding portion, a second feed point for feeding signals arranged adjacent to the grounding portion and separated from the second short circuit segment, a second vertical segment formed by the upward extension of the second short circuit segment, a second horizontal segment formed by horizontal extension of an outer end of the second vertical segment, a second branched vertical segment formed by extension of the second horizontal segment toward the grounding portion, a second rear-end segment formed by extension of the second branched vertical segment toward the second vertical segments, and a second feed segment extended horizontally between the second short circuit segment and the second feed point.
