Wideband parasitic antennas design and realization to improve laptop antenna reception
In laptop antenna reception, the received signal frequently experience significant decrease when laptop antenna is located on a deep fading position in multipath environments. In this paper, we propose a method of using parasitic elements to improve the reception of laptop antenna, which can be incorporated (pasted) at the back panel of laptop screen. The proposed antennas have a wide frequency band, ranges from 2265 MHz to 6233 MHz, to serve all frequencies in WLAN operation. The proposed parasitic antennas exhibit the gain improvement of 1.21 dB at low frequency band (2392.5 MHz) and 2.68 dB at high frequency band (5567.5 MHz). These antennas are able to cover all frequencies in the 2.4 GHz band and the 5.2 / 5.8 GHz band for WLAN systems.
