Description

Ten-band antenna

The present invention relates to an antenna, and more particularly to a ten-band antenna having a low frequency response and a high frequency bandwidth.

Planar Inverted-F Antenna (PIFA), which is commonly used in the market, is manufactured by directly printing metal copper on a printed circuit board through two-dimensional printed circuit board technology. The metal foil is stamped to form a three-dimensional multi-frequency antenna by forming a flat multi-frequency antenna.

By changing the two-dimensional radiator pattern of the printed circuit board or changing the geometry of the three-dimensional radiator stamped by the foil, the antenna can be multi-band transmitted and received. However, in order to satisfy the signal transmission and reception quality and avoid the influence of the surrounding environment, the frequency coordination misalignment thereof, the radiation formed by the antenna formed on the printed circuit board or the antenna formed by stamping the metal foil is bound to have a specific volume. In order to install a PIFA antenna structure with a specific volume, an appropriate space must be reserved inside the electronic device to house the PIFA antenna structure, which is in hindrance to the need for the electronic device to be thin, light and small.

Under the continuous improvement of technology, in order to solve the above problems, the radiator of the antenna is fabricated on a square carrier made of ceramic material.

The signal is fed into the microstrip line 202 and the ground line 203 is electrically connected to the radiator of the carrier 101. Since the high frequency band 102 is located on the right side of the carrier 101, the low frequency band 103 is located on the left side of the carrier 101, and after the antenna 10 is electrically fixed to the printed circuit board 20, the low frequency band 103 is grounded corresponding to the printed circuit board 20. The area of the metal surface 201 is larger than the area of the high frequency band 102 corresponding to the grounded metal surface 201. Therefore, the low frequency band 102 is affected by the grounding shield, and the frequency response of the low frequency band 103 is deteriorated during communication (as shown in FIG. 2). The label A) also makes the bandwidth of the high frequency band 102 not wide enough (only in 6 frequency bands, as shown by the reference B in FIG. 2), so that the transmission and reception signal quality of the entire antenna is lowered, and the bandwidth of the transmission and reception signals is limited.
