1. a co-planar Bow―

  • tie antenna for trap reflector, is characterized in that the co-planar Bow―

    tie antenna of this trap reflector comprises two panels knot radiation patch (1), feeding transmission line (2), medium substrate (5) and trap reflector (6);

    Knot radiation patch (1), feeding transmission line (2) and trap reflector (6) are all on medium substrate (5);

    The shape of two panels knot radiation patch (1) is triangle, two panels knot radiation patch (1) is printed on the same face of medium substrate (5), a slice knot radiation patch is directly connected with the conduction band (3) of feeding transmission line, and another sheet knot paster is connected at the end (10) of feeding transmission line with the ground (4) of the feeding transmission line of medium substrate (5) another side through metalized ground via hole;

    The two-wire line (7) that trap reflector (6) is opened a way by two section terminations is formed, and the conduction band of two-wire line (7) and ground are printed on the two sides of medium substrate (5) respectively;

    Trap reflector load(ing) point (9) is positioned between the input (8) of feeding transmission line (2) and end (10);

    At trap reflector load(ing) point (9), the two-wire line (7) of two section termination open circuits becomes symmetry shape to be placed in the both sides of feeding transmission line (2) respectively, its direction of extension is parallel with the direction that knot radiation patch (1) stretches, and the conduction band of two-wire line (7) is connected with ground (4) with the conduction band (3) of feeding transmission line (2) respectively with ground.
