Compact Dual-Band Monopole Antenna for Wi-Fi Portable Devices

Abstract:

With the rapid development of the wireless communications, the quality of wireless communications services are increasingly improved, which makes people to pay more attention to efficiency and effectiveness of wireless communication system. Recently, some popular portable devices are those defined by 802.11b, 802.11g and 802.11n protocols, such as Wi-Fi card, Wi-Fi card reader and Wi-Fi hard disk. A dual frequency WLAN antenna used for applications of Wi-Fi portable devices is necessary. The reflection loss (Return Loss) of the antenna is a key parameter, therefore, the antenna return loss and bandwidth must meet the conditions of requirements. We use electromagnetic simulation software to simulate and tune the reflection loss of the antenna to more than 10 dB specification. According to the parameters of simulation results, a dual frequency WLAN antenna used for applications of Wi-Fi portable devices is fabricated.
