Here presents a new miniaturized tri‐wideband antenna loaded with metamaterial meander lines. The antenna consists of a rectangular radiation patch loaded with two compact metamaterial components. The three frequency bands are the results of resonances of a rectangular patch at 5.5 GHz, interdigital meander slit at 3.6 GHz, and virtual grounded thin meander stub at 7.5 GHz. More size miniaturization is accomplished by a compact virtual ground structure and cutting the upper and left edges of the substrate. Furthermore, matching at all bands is improved by taking advantage of stepped microstrip feed line and truncated rectangular ground plane. Measured results shows the frequency ranges of 3.32–4.06 GHz (20%), 5.17–6.06 GHz (16%), and 7.17–10.32 (36%). The antenna is analyzed with an equivalent circuit model. In comparison to previous works, this antenna has a simple design, very compact size of 10 mm × 15 mm × 0.8 mm, three wide working bands, and matching levels better than −20 dB at all resonant frequencies.
