A ten-frequency band antenna, comprising:
- a carrier being a ceramic rectangular body and comprising a front face, a top face, a back face and a bottom face, the carrier having a plurality of blind holes defined on the front face and concave into the carrier, and at least one rib between two adjacent blind holes;
- a high-frequency segment comprising an inverse-πshaped radiator, a straight shape radiator, a winding radiator and an L-shaped radiator, wherein the high-frequency segment is arranged on left portions of the front face, the top face, the back face and the bottom face of the carrier if viewing from the front face of the carrier;
- a low-frequency segment comprising a first rectangular radiator, a second rectangular radiator, a third rectangular radiator and a fourth rectangular radiator, wherein the low-frequency segment is arranged on right portions of the front face, the top face, the back face and the bottom face of the carrier if viewing from the front face of the carrier;
- a printed circuit board (PCB) having a top side, a left slanting side, a slanting bottom side, a right short side, a recessed side and a right long side, the PCB having a first face and a second face, the first face having a first ground metal face and a micro strip, the micro strip having a front section and a rear section, the front section having a through hole, the micro strip having a front section extended into the first ground metal face such that a gap is defined between the micro strip and the first ground metal face,
- the first face of the PCB having an opened area with two fixing ends;
- an area portion of the first ground metal face, which is from the left slanting side to the gap being larger than an area portion of the first ground metal face, which is from the recessed side to the gap, a ground line extended on the smaller area portion of the first ground metal face extended from the recessed side to the gap, a separation defined between the ground line and the rear section of the micro strip, the first face having an opened area with two fixed ends;
- an inductor arranged across the separation with one end electrically connecting with the rear section of the micro strip and another end electrically connecting with the ground line,
- wherein the two fixed ends of the opened area of the first face are fixed to the bottom face of the carrier such that the low-frequency segment is corresponding the recessed side and corresponding to the smaller area portion of the first ground metal face extended from the recessed side to the gap and the low-frequency segment is at a free space to enhance a frequency response of the low-frequency segment, the inverse-πshaped radiator, the straight shape radiator, and the winding radiator couple to each other to enhance a bandwidth of the high-frequency segment.
