Ultra-wideband (UWB) antennas with wide rectangular notched-band are proposed in this paper. The rectangular notched-band design is realized by placing dual mushroom-type electromagnetic-bandgap (EBG) structures on the CPW feeding line. The patches of the EBGs are laid on the back size of the substrate and dead against the CPW feeding line. Shorting pins are utilized to connect the patch and the feeding line. Then, the CPW feeding line operates as ground plane for the EBGs. By tuning the two resonant frequencies of the EBG structures and making them merge with each other, a rectangular notchedband is achieved. Research also found that design methodology has the ability to tune the width and the frequency of the rectangular notched-band by adjusting the EBG parameters. Then, three cases of rectangular notchedband designs to reject the wireless local-area network (WLAN, 5.150-5.825 GHz) interference band and the X -band downlink satellite communication band (660 MHz, 7.10-7.76 GHz) were designed by using different EBG parameters. The design methodology can also be utilized to design rectangular notchedband for other interference bands efficiently.
