Dual-band tow layered printed antenna for 2.4/5GHz WLAN operation in the laptop computer

摘要

References(6) A novel dual-band two layered printed antenna for an internal laptop antenna for WLAN operation is presented. The antenna has a simple two layered structure consisting of a spiral strip. The proposed antenna has a low profile and can easily be fed by using a 50Ω microstrip line. It is believed that the size of the antenna is about the smallest among the existing internal laptop antennas for 2.4/5GHz WLAN operation. The antenna occupies a small area of 5mm×12mm on a combined FR4 and foam substrates. The simulated results are in good agreement with the measured results. Compact size, low cost, ease of fabrication and good radiation parameters respect to the previous designs are the most important advantages of the proposed antenna.
