1. a plane dipole sub antenna for double frequency trap reflector, is characterized in that the plane dipole sub antenna of this double frequency trap reflector comprises two panels element radiates paster (1), feeding transmission line (2), medium substrate (5) and trap reflector (6);

  • Element radiates paster (1), feeding transmission line (2) and trap reflector (6) are all on medium substrate (5);

    The shape of two panels element radiates paster (1) is rectangle, two panels element radiates paster (1) is printed on the same face of medium substrate (5), a slice element radiates paster is directly connected with the conduction band (3) of feeding transmission line, and another sheet oscillator 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 microstrip transmission line (7) that trap reflector (6) is not waited by two segment length, the micro-band open-circuit line (12) in the left side micro-band open-circuit line (11) and the right of open-end forms is formed;

    The conduction band of microstrip transmission line (7) and ground are printed on the two sides of medium substrate (5) respectively, the micro-band open-circuit line (12) in the left side micro-band open-circuit line (11) and the right is placed in the both sides of feeding transmission line (2) respectively, and its direction of extension is parallel with the direction that element radiates paster (1) stretches;

    The load(ing) point (9) of trap reflector is positioned between the input (8) of feeding transmission line (2) and the end (10) of feeding transmission line, at trap reflector load(ing) point (9), the conduction band of microstrip transmission line (7) is connected with the ground (4) of feeding transmission line with the conduction band (3) of feeding transmission line (2) respectively with ground.
