| Summary: | Antenna communication technologies were developing fast in recent research area, and these technologies demand high performance antenna to coop with the development. Wireless local area network (WLAN) application is famous term in antenna field nowadays, where this application allowed the users to communicate in long range without wired connection. WLAN demands an antenna with small size and volume, low in cost and weight, easy to design, and can perform efficiently at two distinct frequencies. In this article, the dual-band antenna working at 2.45 and 5.8 GHz was proposed. The proposed antenna consists of L-slots and arm's slot, where these slots greatly influenced the dual-band ability. The combination of 45° of bending angle at all antenna edges and slots can enable the proposed antenna to have good performances in term of return losses, bandwidth percentages, and larger half-power bandwidth (HPBW) values at both frequencies. The proposed antenna works efficiently at 2.45- and 5.8-GHz frequency bands when this antenna gives return loss values of -25.1718 and -28.6754 dB, correspondingly. This device can generate a broad forward beam that covered -62.1 to 62.1° HPBW with 36% bandwidth at 2.45 GHz, whereas at 5.8-GHz band, the HPBW for this antenna covered from -77.4 to 52.2° with 7.04% bandwidth. The proposed antenna suits to be used in WLAN's applications such as in Wi-Fi, Bluetooth, and access point application. The proposed antenna measurement values meet the IEEE 802.11 standard to make this antenna reliable. |
