Abstract
In this article, a novel wideband crossed planar monopole antenna formed by two orthogonal rectangular rings with double step is studied. The antenna design parameters that achieve wideband property are experimentally investigated. Parametric studies have been performed to optimize the impedance bandwidth of the proposed antenna. From the obtained results, the proposed antenna provides a wide bandwidth with isotropic pattern in the Hβplane and directional pattern in the Eβplane. The measured β14 dB impedance bandwidth for return loss is 0.82β2.7 GHz, which can cover various kinds of wireless services such as Cellular (0.824β0.894 GHz), PCS (1.75β1.87 GHz), WCDMA (1.885β2.17 GHz), WiBro (2.3β2.39 GHz), and SβDMB (2.605β2.655 GHz).

This paper presents a low profile wideband top-loading monopole antenna with ring-shaped plate. The ring-shaped plate is used to enhance the impedance matching and to increase the antenna gain, due to the low radiation resistance in the usable band. That is, an additional ring-shaped plate allows us
## Abstract A novel CPWβfed closed rectangular ring monopole antenna with a vertical strip is proposed for WLAN applications. The antenna with a very simple structure is easily fabricated. The measured results explore broadband dualβfrequency operation with (10 dB) impedance bandwidths of 23.4%, ra
A rectangular ring is introduced in an open-ended planar monopole antenna fed by a coplanar waveguide (CPW) in order to achieve broadband dual-frequency operation. Prototypes of the proposed antenna designed for WLAN operation in the 2.4-and 5.2-GHz bands are constructed and tested. The maximum meas
