Abstract
Subject headings
Close
- A concept for multiple-input, multiple-output antenna arrays, integrated in an ultrathin full metal cover laptop computer, is proposed. The antennas are for octa-band wireless wide area network (WWAN) and triple-band wireless localarea network (WLAN) operation. The proposed solution makes use of the gap between the metallic display lid and keyboard chassis to form notch and slot antenna arrays, thereby removing the need for additional protrusions or openings. Simulated aswell as measured performance is presented. The notch antenna array for WWAN exhibits wide impedance bandwidth, with more than 24 dB isolation from 690 MHz to 3 GHz, and a total efficiency better than −2.5 dB. The slot antenna array forWLAN shows more than 12 dB isolation and a total efficiency of more than −3 dB. Both arrays exhibit a very-low envelope correlation coefficient of less than 0.1 within their respective frequency bands.
