Fractal antenna can meet the requirements of designing a multiband, low profile and small antenna. With advancement in wireless technology over the past decade, there is an increasing demand for miniaturization, cost effective, multiband and wideband antennas. Fractal antenna designs can support in meeting these requirements. Fractal antenna design is a geometric pattern that is repeated at eve...

This paper describes a compact triple-band monopole antenna based on Open Complementary Split Ring Resonators (OCSRRs) for Wireless Local Area Network (WLAN) and Worldwide interoperability Microwave Access (WiMAX) applications. The monopole antenna with engraved ground plane is used to cover WLAN frequencies (2.67GHz and 5.47GHz). The resonant frequency of WiMAX (3.43GHz) is achieved by introdu...

This paper proposes the design and analysis of co-axial continuous transverse stub multiband antenna (CCTS) for multiple high frequency Applications. Coaxial continuous transverse stub antenna is used to operate on multiple frequency bands with small size and low cost. This proposed antenna consists of two stubs, arranged longitudinally to form a waveguide skeleton like structure. The advantage...

We present a reconfigurable spiral antenna for use in adaptive MIMO systems. The antenna is capable of changing the sense of polarization of the radiated field.

This integrated antenna design system provide VSWR 2:1 for both 2.4–2.5 GHz and 4.9–5.85 GHz with omni-directional radio patterns. Based on these features, a novel architecture for a dual-band WLAN radio Front-End in portable devices can be achieved. © 2007 Wiley Periodicals, Inc. Microwave Opt Technol Lett 49: ...

A low-profile dual-band half-mode substrate-integrated cavity antenna with a fully shielded textile feeding mechanism is presented for wearable applications. The antenna operates at the lower and upper microwave industrial, scientific and medical (ISM) bands. The cavity geometry is accurately defined with conducting thread through computerized embroidery. Design guidelines are developed for a p...

Synthetic aperture radar (SAR) is an active remote sensing tool operating in the microwave range of the electromagnetic spectrum. It uses the motion of the radar transmitter to synthesize an antenna aperture much larger than the actual antenna aperture in order to yield high spatial resolution radar images (Curlander & McDonough, 1991). It has been applied to military survey, terrain mapping, a...

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 slot line fed planar dipole antenna with a parasitic strip for wide band applications is presented. The presented antenna offers a 2:1 VSWR bandwidth from 1.66 to 2.71 GHz covering the DCS/ PCS/UMTS and IEEE 802.11b/g bands with a gain better than 6.5 dBi. The uniplanar design, simple feeding, and high gain make it a versatile antenna for wireless applications. © 2009 Wiley Periodicals, Inc. ...
