Abstract
AbstractIn this article, a compact design of a printed antenna for the wireless USB dongle over the mobile‐telecoms spectrum is presented. This antenna, which has a small dimension of 21 × 11 mm2, is directly printed on the FR4 substrate, consisting of 2 rectangular patches, 2 parasitic branches and a lumped inductor. In this design, the lumped inductor is used to create a resonant mode at around 770 MHz for LTE700/GSM850/900 bands. The 2 patches and 2 parasitic branches introduce two resonance frequencies that cover 1700‐2700 MHz communication bands. The measured results show a radiation efficiency of >58% and a gain above 1.9 dBi, signifying a good accordance with the simulated ones. Therefore, the proposed antenna is expected to be a good candidate in wireless USB dongle communication applications.
