TI  - A Simple dual-band quasi-Yagi antenna with defected ground structures
AB  - In this article, a dual-band compact quasi-Yagi antenna with defected ground structure (DGS) is proposed.
The proposed antenna has a simple feeding mechanism consists of a microstrip and transmission line. Half of the
driver and director elements are printed on the opposite side of the substrate to ensure good coupling between the
antenna elements and achieve a stable radiation pattern. The ground plane is modified with one rectangular slot below
the microstrip line to form dual-band operation. Also rectangular slots placed on the sides of the ground plane to
improve the matching. The proposed antenna works at f1 = 3.35 and f2 = 6.15 GHz, respectively. The antenna
efficiency is above 88% at f1 and 78% at f2 with bandwidths of 11.8% and 9.7%, respectively. The realized gain is
around 4.3 dBi at both frequency range with an end-fire radiation characteristics. An excellent agreement is observed
between the simulation and measurement results. The proposed antenna is suitable for dual-band operations in wireless
communications systems.
