The time domain modeling of a coplanar wave guide (CPW) fed band-notched antenna for Ultra Wide band (UWB) applications is presented. The annular ring antenna has a dimension of 36x36 mm when printed on a substrate of dielectric constant 4.4 and thickness 1.6 mm. The uniplanar nature and compact structure of the antenna make it apt for modular design. The crescent shaped slot provides a notch i...
A new 6-port “circuit-model” for Coplanar-Slotline Crosses is presented. The model is based on the separation of the two fundamental Coplanar Waveguide (CPW) modes (even and odd) into different ports. It generalizes previous models since it explains the Cross’ behavior even if air-bridges are not used and Slotlines are loaded asymmetrically. The new model is applied to the analysis of the -para...
This paper presents the electrically small U-slot loaded circular microstrip patch antenna with Complementary Split Ring Resonator (CSRR). The technique of U slot loading is used for operating antenna in dual band and CSRR technique to make antenna compact and CSRR for compactness is used. The simple circular patch antenna resonates at 5. 71 GHz with return loss of -11. 38 dB. The proposed ante...
Abstract—An ultra wideband (UWB) coplanar waveguide (CPW) fed rectangular monopole antenna, which is of band notched characteristic for Wireless Local Area Network (WLAN), Worldwide inter-operability for Microwave Access (WiMAX) and the C-band satellite communications, is proposed, fabricated and measured. In order to obtain the desired dual band rejections, a piece of pentagonal slotline and a...
An Antenna is a metallic structure that transmits and receives radio waves. Antennas come in all shapes sizes from tiny microstrip antenna for biomedical applications to very big parabolic reflector antennas satellite communications. A Super Wideband Square Monopole designed on Arlon AD260A FR4 Epoxy with CPW-feed structure. Notched bands are obtained by embedding inverted E-shaped stub, using ...
Abstract We investigate using finite element methods how sub‐micrometer to micrometer‐scale coplanar waveguide (CPW) can be used for the detection of fingerprint spectra very small (of order 10 −14 mL) volumes analytes in terahertz (THz) frequency range. The electric field distribution is investigated near various gap widths between center conductor and ground plane a simulation (ANSYS High Fre...
a newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (uwb) applications. the two band notches of this coplanar waveguide (cpw) fed antenna are achieved by an m-shaped slot (mss) embedded in the radiating element and a c-shaped strip(css) close to ground plane, therefore two very narrow rejected properties in the wireless loc...
In this paper, we introduce a new compact dual-polarized conformal slot antenna fed by two orthogonal Coplanar Waveguide (CPW) semi-discs. To achieve a high isolation between the two ports, a strip is inserted diagonally in the ground plane. The simulations are done using the Computer Simulation Technology (CST) Microwave Studio software. The simulated results show that the proposed antenna pro...
A new ultawideband circular fractal antenna with notched-band characteristics is presented. A notched-band characteristic is achieved by employing a U-shape slot in 50 Ω feed lines. The ultra-wideband impedance matching and compact size have been obtained by using CPW-feed technique and the fractal concept. The measured result of proposed fractal antenna exhibits the ultra wideband characterist...
