摘要：

A compact uniplanar printed dual-antenna for laptop computers is proposed. The dual-antenna, consisting of two symmetric antenna elements and a protruded ground with an embedded T-shaped slot, is printed on a single-layer printed circuit board with a size of only 9 40 mm. The antenna element is a coupled-fed loop antenna with a size of only 9 7 mm. The protruded ground with the embedded T-shaped slot reduces the mutual coupling within two frequency bands. The working mechanism is analyzed in detail for deep understanding. A prototype shows that the measured -10-dB impedance bandwidths are 190 MHz (2.38-2.57 GHz)/1.82 GHz (4.34-6.16 GHz), and the measured mutual couplings are lower than -18/-20 dB at the 2.4- and 5.2/5.8-GHz WLAN bands, respectively. The measured gains and efficiencies are better than 4.1/4.1 dBi and 65%/54% at the 2.4- and 5.2/5.8-GHz WLAN bands, respectively.
