چکیده

A novel and broadband spiral chip antenna is presented in this paper. The size of the proposed antenna is 20× 3.2 × 8mm and is suitable to be embedded in a mobile phone as an internal antenna. Also, this antenna is designed to be installed at the newest mobile handset whose size is 40 × 93mm. The minimization of this antenna was realized by using spiral line structure on FR-4 of dielectric permittivity εr = 4.4. The proposed antenna is SMD type to be easily installed in the practical mobile handset. We use PCB technology which can allow this antenna to be produced massively with low cost. We can get the wideband operation in the upper band by overlapping high order resonances of branch structure. The measured bandwidth (VSWR< 3) of the designed antenna is 160MHz (980–1140 MHz) in the lower band and 1230 MHz (1910–3140 MHz) in the higher band. The antenna has been designed by a commercial software HFSS. DOI: 10.2529/PIERS061006054652
