Design of a dual-band microstrip-fed meandered-tail PIFA for WLAN applications

The design of a novel dual-band PIFA of compact size for WLAN application has been presented. This new miniaturized PIFA is capable to operate in dual-band that cover 2.4-2.4835 GHz band for 802.11/b/g and 5.15-5.825 GHz band for 802.11a (indoor and outdoor) for application. The operation in the upp...

Description
Summary:The design of a novel dual-band PIFA of compact size for WLAN application has been presented. This new miniaturized PIFA is capable to operate in dual-band that cover 2.4-2.4835 GHz band for 802.11/b/g and 5.15-5.825 GHz band for 802.11a (indoor and outdoor) for application. The operation in the upper band is achieved by the introduction of a ground slot which is excited by the same feed used for launching the lower band. The proper choice of dimensions and location of the slot not only introduces new operational band. It also improves the bandwidth and quality of return loss. Using the meandered structure accompanied by a ground slot reduces the overall size of the primary PIFA element to almost 50% of its original size given in . The attributes of reduced size and improved bandwidth are welcome with respect to the intended WLAN application.
