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 filter structure improvement includes a substrate, resonance layers, a grounded layer, a pattern layer, an input electrode, and an output electrode. The substrate has resonance holes in which the resonance layers are disposed. One end of the resonance hole is on the open surface and the other end of the resonance hole is on the short-circuit surface. The grounded layer is on the short-circuit surface, top surface, bottom surface, and side surfaces and is electrically connected to the resonance layers to form a short-circuit end. The input and output electrodes, electrically isolated from the grounded layer, are on the bottom or open surface of the substrate. The pattern layer, resonance layers, and grounded layer are arranged to have electrical properties of a filter structure of mutual coupling such that a desired frequency band is obtained by adjusting the pattern layer and the lengths of the resonance layers.

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.
