Abstract

A low-profile surface-mount metal chip antenna with a symmetric planar inverted-F structure suitable for 2.4 GHz WLAN operation is presented. The proposed antenna is obtained by folding a single metal plate which includes several periodic slots and two-pairs of symmetric soldering strips as the feed and short pins. Due to the two-pairs of symmetric feed and short pins, it is more flexible to be integrated in the system circuit board. Besides, the two-pairs of symmetric pins are also the supporter of the proposed antenna, it leads that the proposed antenna doesn´t need any base and has higher radiation efficiency due to the air substrate. The height of the proposed antenna is 3 mm only, and the bandwidth reaches 190 MHz. It can easily cover the 2.4 GHz band (2400-2484 MHz). Details of the antenna design and the experimental results for the proposed antenna are presented.
