In this paper Micro strip Patch Antenna Array are designed and analyzed for WLAN application, which operating at S-band frequency Range of 2.4 GHz. Antenna arrays are used to achieve higher gain. The larger number of antenna elements, the better gain of antenna array is achieved. In this paper feeding element and power divider is used to design the 4 X 1 micro strip patch antenna array. Micro s...

This article describes a new miniaturized omni-directional antenna with quasi-self-complementary structure for wireless communication applications. A novel ground structure composed of five rectangular plates is proposed to enhance the impedance bandwidth and reduce the antenna size. The proposed antenna is comprised of two patches surrounded by the ground structure. Two metal patches of the an...

In this paper, a wideband electronic beamforming concept applicable for UWB short pulse systems is derived and experimentally demonstrated. In particular, a Finite Impulse Response (FIR)-filter based beamforming network is configured such that an antenna array yields a desired radiation pattern within a predefined frequency range. An experimental verification of a wideband transmission system i...

Combining the ability to localize electromagnetic fields at the nanoscale with a directional response, plasmonic antennas offer an effective strategy to shape the far-field pattern of coupled emitters. Here, we introduce a family of directional multiresonant antennas that allows for polarization-resolved spectral identification of fluorescent emission. The geometry consists of a central apertur...

─ In this paper, a novel ultra-wideband printed monopole antenna (PMA) for the use in a circular cylindrical microwave imaging system is presented. The proposed antenna consists of a square radiating patch and a ground plane with a pair of L-shaped slots and two L-shaped conductor back plane, which provides a wide usable fractional bandwidth of more than 130 % (3.02 GHz 15.21 GHz). By cutting t...

This paper considers synthetic aperture radar (SAR) and other synthetic aperture imaging systems in which a backscattered wave is measured from positions along an arbitrary (known) flight path. The received backscattered signals are used to produce an image of the terrain. We assume a single-scattering model for the radar data, and we assume that the ground topography is known but not necessari...

In this paper we present and evaluate a method for estimation of in-network performance of mobile terminal antennas developed by the Swedish telecom operator Telia. The Telia Scattered Field Measurement (TSFM) Method is intended to give a better estimate of the performance of the mobile terminal antenna as in an in-network fading scenario. The parameter measured from the TSFM method is referred...

Many types of antennas can be used for digital TV receivers; in this article we try to design a double biquad antenna. This is due simple form, easy make, wide beamwidth. In designing receiver the Malang area, an STB device needed, so that analog still receive broadcasts. study, antenna made copper wire, each side length: ¼ ? , with working frequency: 650 MHz. order match impedance 75? coaxial ...

In the field of pattern synthesis, design arrays to synthesis optimized sum and difference patterns in a successive manner is an important problem most radars. Although several researchers published many papers open literature, investigations are made by authors discrete radiators using well-formulated Genetic Algorithm (GA). The practical constraints taken into account amplitude distribution p...
