ABSTRACT
By inserting Yagi-type arrayed-slots on a metallic plate placed on afoam base with a large offset U-L-shapedfeed, a low-cost, surface-mount, planar inverted-F antenna (PIFA), suitable for cellular, PCS, IMT-2000 multi-band operations, is realized. The antenna has a 37 × 25 × 7.5 mm compact size. The proposed antenna can easily be constructed at low cost, and has a low antenna height above the ground plane of the system circuit board. In this case, a large offset U-L-shaped feed line leads to good impedance matching over a wide frequency band. Inserted Yagi-type arrayed-slots on the patch element act as multi-band resonant elements of the antenna. This article presents experimental results of a constructed prototype, covering the usable bandwidths of the cellular (0.824 to 0.96 GHz), GSM (0.86 to 0.88 GHz), DCS (1.71 to 1.88 GHz), PCS (1.85 to 1.99 GHz) and IMT-2000 (1.90 to 2.20 GHz) operations.
