The simulation and measured results show that the antenna offers performance for wideband system from 4...

A new design and experimental results of a microstripfed ultra-wideband Fermi antenna at millimeter-wave frequencies are presented. By utilizing a new microstrip-to-CPS balun (or transition), which provides wider bandwidth than conventional planar balun, the design of microstrip-fed Fermi antenna is greatly simplified. The proposed Fermi antenna demonstrates ultra-wideband performance for the f...

Antennas integrated with active circuitry are usually referred to as active antenna arrays. The integration can be done at different levels, depending on the goal and application. For example, a low-noise amplifier (LNA) is often integrated directly with the antenna for reduced loss and therefore decreased noise figure. Another example is the integration of power amplifiers with antenna arrays ...

In this paper, we introduce a novel printed monopole antenna for ultra-wideband (UWB) applications. The antenna is composed of two overlapped circular disc monopoles with a finite ground plane and fed by a 50 microstrip line. The designed antenna operates over impedance bandwidth (2.9 to 11.6GHz) for return loss S Ω 11 < -10dB. The antenna also shows omni-directional radiation patterns and good...

An investigation of magnetic current distribution of CPW fed arrow shaped UWB antenna is reported. This enables the precise prediction of working principle of UWB antenna, since the traditional UWB antenna simulations ignore important details. The computation was performed numerically for an arrow shaped antenna at different resonant frequencies at various input current phase changes and was fo...

Introduction: Millimetre-wave fibre wireless applications [1] could profit from a small antenna that can be fully integrated with the microwave and optical components of the system. This can lead to smaller and more cost-effective fibre-fed antenna units. Active integrated antennas [2] are another application that could benefit from a directly integrated antenna. Printed antennas are the obviou...

This paper presents the study on a slot-etched rectangular patch antenna directly fed by the 50 Ω semi miniature A-type (SMA) co-axial connector for wireless systems. The dual frequency behaviour by etching the slots on plane patch surface is studied experimentally. The proposed patch antenna has also achieved 28% compactness with a gain of 9.74 dB. Other antenna parameters such as antenna inpu...

This paper describes the antenna design for RF power harvesting system. The design goes through three phases designing of antenna, matching network and rectifier. A dual band Microstrip antenna suspended above ground plane is designed to operate in GSM 1.8 and ISM 2.4 GHz bands. The antenna incorporates the capacitive feed strip which is fed by coaxial probe technique where the inductive impeda...
