This work proposes a novel quad-band microstrip patch antenna for wireless local area network (WLAN), worldwide interoperability for microwave access (WiMAX), C and X applications. It is composed of a modified rectangular patch antenna and two parasitic elements which are both printed on one side of a FR4 substrate, a ground plane on other side on which a U-shaped slot is etched. The proposed antenna,...
This paper, present the resonant and the radiation characteristics of superconducting rectangular microstrip antenna printed on uniaxailly anisotropic substrate using an electromagnetic approach based on cavity model in conjunction with electromagnetic knowledge. The cavity model combined with London's equations and the Gorter-Casimir two-fluid model has been improved to investigate the resonant characteristics...
A compact ultra wideband (UWB) antenna with dual band-notched characteristics is proposed and investigated in this article. The antenna is composed of a V-shaped patch with a stair case defect fed by a 50 Ohm microstrip line and a semicircular defected ground plane printed, respectively, on the top and bottom layer of the substrate. The dual band-notch function at WiMAX (3.17–3.85 GHz) and ITU (7...
This paper proposes a new design approach of a hexagonal fractal ring patch antenna for dual-band applications. The proposed antenna operates at two resonant frequency bands to cover 2.45-GHz WiFi and 3.5-GHz WiMax applications. To achieve dual-band operation, a first-iterative fractal-ring radiating patch is printed on a substrate layer coupled with another identical fractal ring printed in the other...
This paper presents a study of a printed X-shaped monopole antenna. The analysis has started from considering a strip fed conventional single band Rectangular Microstrip Antenna (RMSA) resonating at 2.45 GHz commonly used in WLAN applications. The antenna has been transformed to a monopole structure that has yielded a larger bandwidth. In the second part, triangular slots were introduced to the RMSA...
In this paper, a novel and low profile CPW-Fed triple-band microstrip antenna for wireless applications is proposed. The proposed antenna is implemented on FR4-Epoxy dielectric substrate with dimensions of 24×40 mm2 and generates three desired resonant frequencies at about 2.44 GHz, 3.56 GHz and 5–6 GHz for WLAN and WiMAX applications. Numerical results for the return loss and 2D radiation patterns...
In this work, a dual band Microstrip patch implantable antenna for biomedical applications has been presented to operate in both Medical Implant Communications Service (MICS) with a range of 402–405 MHz and 2.4–2.5 GHz band chosen among the Industrial Scientific and Medical (ISM). A rectangular antenna has been first simulated to operate in MICS band with dimensions of 179.7 × 228.3 × 1.63 mm, then,...
