An assembly of a chip antenna and a circuit board includes a chip antenna and a circuit board. The circuit board includes a ground layer. The ground layer includes a hollow region formed adjacent to a periphery of the ground layer. The hollow region of the ground layer can be used for configuring an input impedance of the circuit board. The chip antenna is disposed in the hollow region of the ground layer, electrically connecting to the ground layer. The chip antenna includes input impedance. The input impedance of the chip antenna is adjustable to achieve a conjugate impedance match between the chip antenna and the circuit board such that the circuit board and the chip antenna can simultaneously radiate electromagnetic energy.

Assembly of chip antenna and circuit board

A dual-band dipole antenna adapted to be disposed on a dielectric substrate comprises two substantially rectangular radiating metallic sheets and a coaxial transmission line. The substantially rectangular radiating metallic sheets are symmetrically disposed on two sides of the dielectric substrate with respect to the central line thereof, wherein each of the radiating metallic sheets further has a feeding point and a U-shaped slot. One feeding point is disposed opposite to the other feeding point, and the opening of the U-shaped slot is in the direction of the feeding point for dividing the substantially rectangular radiating metallic sheet into a larger sub-metallic sheet and a smaller one, wherein the former serves to generate a first (lower frequency) operating mode of the dual-band dipole antenna, and the latter serves to generate a second (higher frequency) operating mode thereof. The coaxial transmission line has a core conductor and an external ground conductor which are respectively connected to the feeding points.

Dual-band dipole antenna

A dual-band dipole antenna, which is adapted to be disposed on a dielectric substrate, comprises two substantially rectangular radiating metallic sheets and a coaxial transmission line. The substantially rectangular radiating metallic sheets are symmetrically disposed on two sides of the dielectric substrate with respect to the central line thereof, wherein each of the radiating metallic sheets further has a feeding point and a slit. One feeding point is disposed opposite to the other feeding point, and the slit extends from one edge of the substantially rectangular radiating metallic sheet to the interior thereof in the direction of the feeding point so that a longer path and a shorter one are formed on the substantially rectangular radiating metallic sheet, wherein the longer path serves to generate a first (lower frequency) operating mode of the dual-band dipole antenna, and the shorter path serves to generate a second (higher frequency) operating mode thereof. The coaxial transmission line has a core conductor and an external ground conductor which are respectively connected to the feeding points.
