A novel probe-fed tunable broadband antenna using stub loaded configuration

In this paper, a novel broadband microstrip patch antenna (MPA) using stub loaded configuration is proposed to enhance the bandwidth of antenna. This antenna is designed for circular radiating patch of 18.2 mm radii to achieve broadband frequency 2.285-2.45 GHz which supports IEEE 802.11 WLAN communications. The percentage bandwidth improves by using variable stub length and fixed width on circular patch antenna. Furthermore, the bandwidth enhanced by 7.2 percent at resonant frequency 2.3 GHz.
