A microstrip‐to‐slotline transition technique is presented, for the coupling of a circularly polarized circular slot antenna in the ultrahigh frequency band.The fundamental TE11 mode of the circular slot antenna is investigated, using the magnetic current flow in the slot. In the proposed design, circular polarization (CP) is generated using a proper c‐strip metal, within the circular slot structure, and connecting a strip metal to the circular slot edge, at −45° to the feeding slotline. The direct slotline feed is coupled to a 50‐Ω microstrip line, on the opposite side of the substrate. Simulated and measured results indicate that the proposed structure achieves good CP radiation, in the TE11 mode. The impedance bandwidth and the 3‐dB axial‐ratio bandwidth for the design are approximately 22.1% and 2.5%, respectively. © 2012 Wiley Periodicals, Inc.

A novel design of a dual-band array antenna for Wireless Local Area Network and Worldwide Interoperability for Microwave Access applications is presented in this article. The antenna operates at 3.5 dBi (the lower band) and 5.8 GHz (the upper band), with gains of 7.8 and 5.5 dBi, respectively. The corresponding percentage bandwidths are 2.85 and 2.40%. The overall length of the feeding network was reduced significantly because the elements in the array are closer to each other, with a separation of less than k eff /4. There is good agreement between simulation and measurement results. The results of the surface current study also are presented.

In this paper, A dual band metamaterial antenna with circular polarization is proposed. The antenna consists of a circular patch with etched circular slot printed on an infinite ground plane. The metamaterial property is imposed onto the antenna with the used of series capacitive slot and a shorted inductive via. The circular polarization is obtained at the zero order mode resonance (ZOR) frequency (2.42 GHz) and a linear polarization at negative order mode resonance (NOR) frequency (2.15 GHz). A realized gain of 5.88 dB and 0.877 dB is obtained at ZOR and NOR respectively. An efficiency of 86% and 44% is obtained at 2.42 GHz and 2.16 GHz respectively. Details of the antenna design and approach are described, and the simulated and measured results for the loaded and unloaded antenna are discussed and compared. The antenna is suitable for WLAN application (2.39 GHz-2.45 GHz).
