This paper presents a rectangular-shaped printed monopole antenna with circular polarization for Wi-Fi (2.4–2.484 GHz) and WiMAX (3.3-3.7 GHz) bands. The antenna relies on asymmetric arrangement of the patch with respect to the microstrip feed, in order to generate circular polarization. Dual-band (Wi-Fi and WiMAX) operation is enabled by inserting a slit in the corner of the ground plane. Simulation results show a bandwidth increase of 15.9% (2.2–2.58 GHz) for Wi-Fi, and of 24.16% (3.13–3.99 GHz) for WiMAX applications. Furthermore, beamwidths at the axial ratio of 3 dB equal 48˚ and 51˚ for the x-z plane and y-z planes, respectively.

Purpose The purpose of this paper is to present a new dual-band printed monopole antenna with a partial ground with two notched bands based on electromagnetic band gap (EBG) structures. A new type of EBG antenna with radiation patterns and antenna gains over the operating bands has been developed. Design/methodology/approach The proposed antenna consists of a pair of EBG structures using a transmission line model. The proposed antenna is designed on an FR4 substrate with a thickness of 1 mm and permittivity (er) = 4.3. Findings The measured results show good dual-band operations with −10 dB impedance bandwidths of 9.1 and 36.2 per cent centered at 2.45 and 6.364 GHz, respectively, which covers the wireless local area network (WLAN) operating bands. Originality/value A new type of EBG antenna with radiation patterns and antenna gains over the operating bands has been developed.

Abstract A microstrip line –fed broadband dual circular polarized, two port printed monopole antenna is presented. The antenna consists of a ground plane with arrow shaped stub at the corner and a pair of inverted L-shaped feed lines. The 3dB axial ratio bandwidth of the antenna is about 58%(1.7GHz-3.1GHz) in which the return loss and isolation are better than 10dB and 12dB respectively. A parametric study of proposed antenna’s geometric parameters is given for understanding of the antenna performance. The realize gain, reflection coefficient (S 11 ) and transmission coefficient (S 21 ) are higher than 1, 10 and 12dB respectively within the entire axial ratio bandwidth (ARBW).
