In this article design and optimization of square printed monopole antenna for wireless application is proposed. Theory of characteristics mode (TCM) is used for analysis of current modes on the antenna. TCM analysis shows that beveled ground plane improves the impedance bandwidth. The antenna operates over the frequency range from 1.860 GHz to 5 GHz for a VSWR ≤ 2, covering the GSM (1900-1990M...

Band-notch characteristic has been of great interest recently to overcome the electromagnetic interference of Ultra-wideband systems (UWB) with other existing ones. In this paper, we present a novel microstrip-fed antenna with band rejection property appropriate for UWB applications. Band-notch characteristic has been achieved by adding a rectangular resonant element to the ground section. A pr...

In this work, a design method of an Ultra-Wideband (UWB), low-noise amplifier (LNA) is proposed exerting the performance limitations of a single high-quality discrete transistor. For this purpose, the compatible (Noise F , Input VSWR Vi, Gain GT ) triplets and their (ZS , ZL) terminations of a microwave transistor are exploited for the feasible design target space with the minimum noise Fmin(f)...

In this paper, a new compact wideband monopole antenna is presented for wireless communication applications. This antenna comprises of a new radiating patch, a new arc-shaped strip, microstrip feed line, and a notched ground plane. The proposed radiating patch is combined with a rectangular and semi-circular patch and is integrated with a partial ground plane to provide a wide impedance bandwid...

A single-arm rectangular spiral antenna is analyzed using the finite-difference time-domain method. The spiral is printed on a finite-size dielectric substrate backed by a finite-size conducting plane. Both the substrate and conducting planes are square with a side length of less than 0.6 0 ( 0: wavelength in free space). The radiation pattern is dependent on the outermost arm peripheral length...

The need for directional antennas possessing high gain, wideband and circular polarization characteristics for different wireless applications has increased considerably. In this research paper, a slotted coaxial line fed cavity backed U-shaped cross dipole antenna is developed to achieve wide bandwidth and reconfigurable circular polarization. The cross dipole consists of two orthogonal U-shap...

Antenna arrays that incorporate MIMO technology for indoor–outdoor network interconnection on the same terminal, i.e., for DCS 1800, PCS 1900, WCDMA, 3G, 802.11a/b/g, Bluetooth R , ZigBee VR , WiMAX, and UWB standards, are proposed. Staircase profile printed circuit antennas, monopoles (PCM), and slots (PCS) with VSWR < 2 bandwidth mainly from 1.12 to 10.1 GHz are previously designed, simulated...

This paper focused on the coaxial probe fed square patch microstrip antenna characteristics have been studied with and without dielectric Superstrates. The dielectric constant of the substrate and Superstrate material is used same for designing of square microstrip patch antenna. The antenna designed frequency is 2.4GHz(ISM band) using transmission line model. In this paper experimentally inves...
