Multiband miniature coplanar waveguide curved bow-tie slot antenna for 802.11a-802.11b wireless applications

The design and development of a novel dual-band coplanar waveguide (CPW)-fed bow-tie shaped slot antenna for broadband wireless applications is presented. The antenna operates in IEEE 802.1 1b (2.4-2.5 GHz) and 802.11 a (5.1-5.9 GHz) frequency bands and is aimed to cover a gap in the multi-band wireless applications domain. Simulation work has been performed using commercially available three-dimensional electromagnetic tools and prototypes have been built in order to explore the actual performance of this novel antenna. Satisfactory agreement in simulation and experimental results is shown. The antenna can easily be attached on the backplane of PDAs (Personal Digital Assistants), smartphones or notebooks, to meet the users' needs for wireless connectivity in a small form factor.
