Coplanar Inverted-F Antenna With Open-End Ground Slots for Multiband Operation

This letter reports on a new idea to achieve multiband operation of a coplanar inverted-F antenna (CIFA). In the proposed approach, a microstripline is used to feed the primary CIFA radiator. This feeding arrangement allows for a flexible coupling of the feed to open-end slots in the finite-size gro...

Description
Summary:This letter reports on a new idea to achieve multiband operation of a coplanar inverted-F antenna (CIFA). In the proposed approach, a microstripline is used to feed the primary CIFA radiator. This feeding arrangement allows for a flexible coupling of the feed to open-end slots in the finite-size ground to launch new resonant frequencies. Two configurations of meandered-tail CIFA with ground slots for WLAN and WiMAX applications are designed, fabricated, and experimentally tested to validate the proposed technique. Good agreement between the simulated and experimental results confirms the practical feasibility of the proposed multiband antenna design.
