A very low profile antenna with a simple structure and operation, for use inside a handheld mobile phone, is presented. The antenna achieves a triple-band response, covering the E-GSM (880–960 MHz), DCS (1710–1880 MHz) and PCS (1850–1990 MHz) bands for a voltage standing wave ratio less than 3 and a total radiation efficiency of more than 50%, in all bands. Because of its novel design and structure it occupies only 1.15 cm3 of volume. Computed and measured results are presented and compared.
