چکیده
A new design of a dual-band printed dipole antenna with integrated balun is presented in this study. The antenna in simple form is composed of a printed dipole, integrated balun, a Γ-shaped feed, and a square-shaped ground plane, which achieves a fundamental resonance at ۲.۴ GHz frequency. A pair of rectangular-shaped resonators are positioned on two sides of the Γ-shaped feed in the second designing step innovatively to accomplish the additional resonance at ۵.۵ GHz as the second frequency band of the WLAN. Two electromagnetically coupling mechanisms prepared between the Γ-shaped feed and dipole arms, and rectangular-shaped resonators, which lead to creating two operating frequency bands. An equivalent circuit and a parametric study presented to explain the antenna performance in this work. Experiments approve that the proposed dual-band antenna has two impedance bandwidths of ۱۴.۱% (۲.۲۳-۲.۵۷ GHz) and ۲۵.۷% (۴.۸۳-۶.۲۶ GHz) with average gains of ۱۲.۱۰ dBi and ۶.۳۶ dBi over the first and second frequency bands, respectively, which is cover the ۲.۴/۵.۵ GHz WLAN frequency bands successfully.کلیدواژه ها
