| Abstract |
In this paper, a step type driver dipole antenna with a tapered balance and unbalance (balun) by a coplanar waveguide (CPW) to coplanar strip (CPS) transition is proposed. The proposed antenna consisted of step type driver, a CPW to CPS transition and tapered balun. The proposed antenna is realized the multi and wide resonate frequency band to introduce the step type driver and tapered balun. The step type driver is acted as a director too. This antenna could be more easily designed than the conventional printed quasi-Yagi dipole antenna. The operating frequency bandwidth was 650 [MHz] (2.65~3.3 GHz), 900 [MHz] (4.7~5.6 GHz) under a return-loss criterion of less than 10 dB. The measurements of the proposed antenna exhibited good results in the wideband operating frequency and radiation pattern. The proposed antenna can support wireless communications applications. |
