1. the coplanar Bow―

  • tie antenna of broadband plane of double frequency trap reflector, is characterized in that the coplanar Bow―

    tie antenna of broadband plane of this double frequency trap reflector comprises two knot radiation patch (1), feed transmission line (2), medium substrate (5) and trap reflector (6), knot radiation patch (1), feed transmission line (2) and trap reflector (6) are all on medium substrate (5), the shape of two knot radiation patch (1) is triangle, two knot radiation patch (1) are printed on the same face of medium substrate (5), a slice knot radiation patch is directly connected with the conduction band (3) of feed transmission line, and another sheet knot paster is connected at the end (10) of feed transmission line with the ground (4) of the feed transmission line of medium substrate (5) another side through metallization ground connection via hole, the two-wire line (7) that trap reflector (6) is made up of the two segment length left side two-wire open-circuit line (11) that grade, terminal are not opened a way and the right two-wire open-circuit line (12) forms, the conduction band of two-wire line (7) and ground are printed on respectively the two sides of medium substrate (5), left side two-wire open-circuit line (11) and the right two-wire open-circuit line (12) are placed in respectively the both sides of feed transmission line (2), and its direction of extension is parallel with the direction that knot radiation patch (1) stretches, first load(ing) point (9) of trap reflector and second load(ing) point (13) of trap reflector are all positioned between the input (8) of feed transmission line (2) and the end (10) of feed transmission line, at first load(ing) point (9) of trap reflector, the conduction band of left side two-wire open-circuit line (11) is connected with the conduction band (3) of feed transmission line (2) and the ground (4) of feed transmission line respectively with ground, at second load(ing) point (13) of trap reflector, the conduction band of the right two-wire open-circuit line (12) is connected with the conduction band (3) of feed transmission line (2) and the ground (4) of feed transmission line respectively with ground.
