A dual-band electrically small antenna based on impedance matching circuit is proposed. Which is fed by coplanar waveguide (CPW). The antenna includes two twin-spiral type slot-line short stubs and three open-circuited series-stubs with slot-line loaded at the central feed line of the CPW as impedance matching network. The total size of the antenna is 12.45 mm x 13.05 mm x 0.8 mm, with K alpha = 0.45 and 0.95 at 2.4 GHz and 5 GHz respectively. By the introduction of the proposed impedance matching network, the syntonic frequency of the antenna is achieved at 2.4 GHz and 5 GHz. And the measured bandwidth of Sit < -10 dB is about 7.5% and 12% of the two resonant frequencies. The proposed antenna has a very small ground plane (0.9 mm x 1.8 mm). And it is appropriately applied to wireless communication for considerable radiation efficiency. (C) 2017 Elsevier GmbH. All rights reserved.
