Abstract
A novel dual-frequency monopole antenna, with a low profile and also with a small transverse size, is proposed. Firstly, by investigating and utilising a taper meander line antenna with a very large vertex angle, the antenna height is reduced to 15 mm. Secondly, by wrapping it in a box-like structure, the antenna transverse width is reduced to 12 mm. Thirdly, by introducing another geometrically complementary meander line branch, the second resonant mode is enhanced. Finally an antenna with dimensions of 15×12×7 mm is designed, and good impedance bandwidth performance for GSM (890-960 MHz) and DCS (1710-1880 MHz) bands is observed.
