Abstract: A metal structure includes a patterned molybdenum tantalum oxide layer and a patterned metal layer. The patterned molybdenum tantalum oxide layer is disposed on a first substrate, in which the patterned molybdenum tantalum oxide layer includes about 2 to 12 atomic percent of tantalum. Both of an atomic percent of molybdenum and an atomic percent of oxygen of the patterned molybdenum tantalum oxide layer are greater than the atomic percent of tantalum of the patterned molybdenum tantalum oxide layer. The patterned metal layer is disposed on the patterned molybdenum tantalum oxide layer.

Abstract: 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.

Abstract: The invention relates to a stacked circularly polarized antenna structure (10). The stacked circularly polarized antenna structure (10) comprises a first antenna (1), a second antenna (2), and an adhesive element (3). The adhesive element (3) is adhered between the first antenna (1) and the second antenna (2) to stack and form a stacked circularly polarized antenna structure (10) having the first antenna (1) and the second antenna (2) made of ceramic material with the same dielectric constant, having two feeding elements to reach circular polarization and enhance antenna bandwidth, and stacking the two antennas (1, 2) together to form two resonance frequencies.

Abstract: 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.

Abstract: A ceramic antenna includes a carrier and a radiation metal part. The carrier includes a plurality of long sides and a plurality of short sides. The radiation metal part is arranged on the carrier. The short sides are in arc-shape. Therefore, the long sides and the short sides are not easily broken when moving the ceramic antenna or covering the radiation metal part on the carrier. The defective rate of the ceramic antenna is decreasing.
