摘要：
A novel coplanar waveguide-fed ultra-wideband antenna with triple band-notched function centred at 3.5, 5.5 and 7.5 GHz is proposed. It has small size of 26 x 26 mm(2). This antenna consists of an elliptical radiator and a square ground plane with an elliptical slot on one side of the substrate. Besides, two circles with a radius of 2 mm were dug from the edge of the outer ellipse to realise the bandwidth requirement. To avoid interference fromWorldwide Interoperability for Microwave Access, a single open-ended elliptical arc-shaped slot was etched on the top side of the ground. Moreover, another elliptical arc-shaped slot notched at wireless local area network band was etched on the elliptical radiator and two systemically C-shaped slots working at 7.3-7.7 GHz was embedded on the structure. Measured voltage standing wave ratio shows the working frequency range was from 3.1 to 13.5 GHz except for notched bands of 3.35-3.8, 5.1-5.9 and 7.35-7.8 GHz.
