Multiband miniature coplanar waveguide slot antennas for GSM-802.11b and 802.11b-802.11a wireless applications

摘要

The design and development of two novel dual-band coplanar waveguide (CPW)-fed slot antennas for broadband wireless applications is presented. The first antenna operates in GSM (1.7-1.9 GHz) and IEEE 802.11b (2.4-2.5 GHz WLAN) frequency bands, while the second antenna operates in the 802.11b (2.4-2.5 GHz) and 802.11b (5.1-5.9 GHz) frequency bands. These antennas are aimed to cover the gap in the multiband 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 these two antennas. Satisfactory agreement in simulation and experimental results is shown. These antennas can easily be attached on the backplane of PDAs, smartphones or notebooks, to meet users' needs for wireless connectivity in a small form factor.
