A compact dual-band patch antenna is proposed and measured in this paper. The proposed antenna employs a U-shaped slot and two mitered corners to achieve two operating frequency bands, 2.30 ∼ 2.50GHz and 4.50 ∼ 6.36GHz, which meet the specifications of IEEE 802.11b/g/a standard for WLAN applications. Full wave analysis is performed to simulate the characteristics of the proposed antenna using C...

Abstract—Impact of electromagnetic interference on front-end receiver behaviour is theoretically and experimentally studied outside the bandwidth of the antennas. Microwave chaotic generation is observed. Under certain conditions, reflected waves combined to the non linearity of the front-end receiver leads to a chaotic signal generation between the antenna and the front-end receiver. Different...

In this paper, a microstrip patch antenna array on ground with PBG is simulated and measured. It is shown that the photonic band-gap (PBG) can suppress harmonics and optimize the current distribution on the patches. As a result, the gain of the antenna array is improved and the side-lobe level is reduced. © 2004 Wiley Periodicals, Inc. Microwave Opt Technol Lett 41: 127–130, 2004; Published onl...

A new antenna, integrated with the shielding structure of the de ice, is described. Despite its compact dimensions, it has excellent radiation properties. 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 27: 155 157, 2000.

A microstrip-fed printed bow-tie antenna is presented in order to achieve wide bandwidth, high gain, and size reduction. A comparison between the bow-tie and the quasi-Yagi (dipole and director) antennas shows that the bow-tie antenna has a wider bandwidth, higher gain, lower front-to-back ratio, lower cross-polarization level, and smaller size. Two-element arrays are designed and their charact...

AbstructMeasurements of the surface deviations of a parabolic antenna by microwave holography have been corrected for the effects of an enclosing radome. The largest correction, which is due to diffraction from the metal space frame, is made by using a model computed from the radome structure. This model accounts for the changing diffraction as the antenna is scanned during the interferometric ...

A wideband planar monopole antenna with an L-shape ground plane is presented. The antenna also has a frequency-notching characteristic. By etching a half-wavelength U-shaped slot in the interior of the radiation element, the frequency-notching characteristic has been created. This paper presents the design and experimental results of the proposed antenna. Moreover, the study also investigates t...

The design of a simple small-size antenna for worldwide interoperability for microwave access (WiMAX) application is presented in this paper. The antenna covers the 3-5 GHz WiMAX band. The proposed printedtype antenna is based on a 1.6 mm-thick FR4 epoxy substrate with dimensions W=25 mm and L=40.5 mm. It has a rectangular split-ring slot enclosed inside a rectangular patch.
