A very‐low‐profile (VLP) broadband planar antenna is developed for DCS‐1800 and IMT‐2000 handsets. The VLP planar antenna consists of an S‐strip and a T‐strip, which are separately printed on the two sides of a thin substrate. The antenna height is only 4.8 mm which is much lower than previously published antenna configurations. The VLP planar antenna can achieve a bandwidth of ∼30% for return loss < ‐ 10 dB.
