A Multi-band Inserted Yagi-type Arrayed-slots PIFA Antenna Using a Large Offset Rectangular L-shaped Feed

By inserting Yagi-type arrayed-slots on a metallic plate placed on a foam base with a large offset U-L-shaped feed, a low-cost, surface-mount, planar inverted-F antenna (PIFA), suitable for cellular, PCS, IMT-2000 multi-band operations, is realized. Th...
Along with monopole, patch and slot antennas, the inverted-F antenna (IFA) has become of primary importance for portable and handheld wireless communication units. It is known as a high-efficiency, quasi-omni-directional antenna, with a height of approximately 0.05 to 0.1λ, which is 2.5 to 5 times shorter than a quarter-wave...
