A surface-mounted signal transceiver module with multi-signal feed-in includes an antenna unit, a circuit board and a signal-integrating component. A radiation layer is arranged on a substrate-front face of the antenna unit. A ground layer is arranged on a substrate-back face. A first-feed-in line and a second-feed-in line are arranged on a substrate-side face. A first-ground face arranged on a circuit-board-front face of the circuit board is connected to the ground layer. A first contact and a second contact of the circuit board are connected to the first-feed-in line and the second-feed-in line respectively, and electrically connected to a fixing-connecting area arranged on a circuit-board-back face. The signal-integrating component is electrically connected to the fixing-connecting area, and connected to the first-feed-in line and the second-feed-in line through the first contact and the second contact respectively, to integrate signals sent through the first-feed-in line and the second-feed-in line.

A surface-mount multi-band antenna includes a carrier, a first radiator, a second radiator, and a third radiator. The first radiator, the second radiator and the third radiator are respectively arranged on faces of the carrier. The first radiator includes a first rectangular region and a second rectangular region arranged on the bottom face of the carrier. The second radiator includes a third rectangular region and a fourth rectangular region on the bottom face. The second rectangular region has an opened area on the surface of the bottom face to provide coupling effect to increase bandwidth. One end of the fourth rectangular region forms a ground point and has a separation of 0.75 mm with the second rectangular region to provide matching. The fourth rectangular region has a length of 9.9 mm to add one more mode.

Antenna

A surface mount device multiple-band antenna module includes a substrate and a carrier. The substrate has a first grounding metal surface and a first micro-strip line on a side thereof. The first grounding metal surface has a second micro-strip line connected thereto. There is a space between the first micro-strip line and the second micro-strip line. The substrate has a second grounding metal surface on the other side thereof. The carrier is made of ceramic material with high dielectric constant, which has a first radiative metal portion, a second radiative metal portion and a third radiative metal portion. The carrier is electrically connected with the substrate. The joint of the first radiative metal portion and the second radiative metal portion is electrically connected to the first micro-strip line. The third radiative metal portion is electrically connected to the second micro-strip line. Thus, the multiple-band antenna module is obtained.
