Abstract

A four-sided folded, slotted and shorted rectangular patch antenna for 3G mobile handsets is described. The antenna provides a 17.65% bandwidth at S&#x2081;&#x2081; < -10 dB from 1885 MHz to 2250 MHz, which completely encompasses the desired UMTS frequency band (1920-2170 MHz). The proposed antenna is minimised to a volume of 30 × 30 × 6 mm, which is about 0.2 wavelengths at the centre frequency 2045MHz, while the height from the antenna to the ground plane is about λ/15 at the centre frequency (10mm). The experimental and simulated results on a finite ground plane show good agreement. The effect of varying key geometry parameters of the proposed antenna is also discussed.
