Slotted square patch printed monopole antenna with dual band capabilities for WLAN application

WLAN demands an antenna with small in size and volume, low in cost and weight, easy to design, and can perform efficiently at two distinct frequencies. In this paper, the dual band antenna work at 2.45 GHz and 5.8 GHz were proposed. The proposed antenna consists of L-slots and arm´s slot where these slots greatly influenced the dual band ability. With combination of 45° of bending angle at all antenna edges and slots can enables the proposed antenna to have good performances in term of return losses, bandwidth percentages and larger HPBW values at both frequencies. The proposed antenna is suits to be used in WLAN´s applications such in Wi-Fi, Bluetooth and Access Point (AP) application.
