Optimization of dual-band CPW Pentagonal patch antenna with slots for WiMAX and WLAN applications
Beside low cost and easy to fabricate, there isn't enough bandwidth in any single antenna to accommodate all frequency ranges for basic rectangular antenna. The antenna with dual band frequency is proposed. This research presents various co-planar waveguide pentagonal microstrip patch antenna d...

Beside low cost and easy to fabricate, there isn't enough bandwidth in any single antenna to accommodate all frequency ranges for basic rectangular antenna. The antenna with dual band frequency is proposed. This research presents various co-planar waveguide pentagonal microstrip patch antenna designs with multiple slots structure (MSS) techniques for dualband 3.5 GHz Worldwide Interoperability for Microwave Access (WiMAX) and 5.8 GHz Wireless Local Area Networks (WLAN) application.
