摘要： A chip-type antenna structure includes a baseboard, a matching element, a radiation single body and a frequency-modulation element. The baseboard includes a first-ground surface, a first-clearance area and a signal-feed-in unit. A second-ground surface, a second-clearance area, a third-ground surface and a plurality of via holes through the baseboard and electrically connected to the first-ground surface and the second-ground surface are arranged on the other side of the baseboard. The matching element is electrically connected between the signal-feed-in unit and the first-ground surface. One side of the radiation single body is electrically connected to the signal-feed-in unit through the via holes. The other side of the radiation single body is electrically connected to the third-ground surface. The frequency-modulation element is electrically connected between the second-ground surface and the third-ground surface to adjust the frequency-modulation element to adjust a receiving-transmitting frequency of the chip-type antenna structure.

摘要： An enhanced printed circuit board monopole antenna includes a baseplate, a signal feed-in unit, a first-radiation unit, a second-radiation unit and an auxiliary ground unit. The first-radiation unit and the second-radiation unit are arranged on a front side and an edge side of the baseplate. The auxiliary ground unit is arranged on the edge side and electrically connected to a first ground unit and a second ground unit on the baseplate. Adjusting the first-radiation unit controls 88 MHZ-60 GHZ frequency range impedance, resonant frequency, bandwidth and radiation effect. According to the frequency wave length (1λ, ½λ, ¼λ or ⅛λ) formed by the first-radiation unit and the second-radiation unit cooperating with each other, controlling 88 MHZ-60 GHZ frequency range achieves the predetermined target impedance, resonant frequency, bandwidth and radiation efficiency. The antenna radiation efficiency can be increased effectively.

摘要： A single feed-in dual-band antenna structure includes a first radiation unit, a basal plate and a plurality of matching components. The basal plate includes a front side, a back side and an edge side. A first ground unit, a signal feed-in unit, a second radiation unit and an electrode part are arranged on the front side. A third radiation unit is arranged on the edge side. A second ground unit is arranged on the back side of the basal plate. The first radiation unit is electrically connected to the electrode part. The first radiation unit is adjusted to control the 2.45 GHZ frequency range impedance, resonant frequency, bandwidth and radiation effect. The third radiation unit frequency wave length controls the 5 GHZ frequency range to achieve the predetermined target impedance, resonant frequency, bandwidth and radiation efficiency. The antenna size can be reduced effectively.

摘要： A method of manufacturing chip antenna and a structure of the chip antenna. The method includes the following steps: preparing a substrate, drilling a plurality of rows of external through holes and internal through holes arranged longitudinally, forming fishing grooves at the predetermined distance between every two of the internal through holes arranged longitudinally, electroplating a metal material on the external through holes and the internal through holes, to form a conductive layer. Afterward, a circuit layer is formed on the conductive layer by exposure, development, and etching techniques. An ink is printed on the substrate after the circuit layer finished, and the ink cover parts of the circuit layer and parts of the substrate exposed, to form a solder mask and a recognition pattern layer. Finally, a longitudinal cutting line and a horizontal cutting line are cut on the substrate, and to form a chip antenna.
