This paper covers two aspects of microstrip antenna design. The first is the analysis of trapezoidal patch microstrip antenna with V-shaped slot which operate at the centre frequency of 5.5 GHz. The second aspects are the analysis and design of inverted V-shaped slot cut trapezoidal microstrip antenna operates at centre frequency of 4.1 GHz. The simulation has been done through IE3D simulator. ...

This paper describes the comparision of a microstrip-fed monopole ultra wideband antenna with and without notch. In case of notch the notch-band characteristics is achieved by Cshaped ring resonator. The paper gives better understanding of antenna parameters such as return loss, VSWR etc., and its variation in performance of antennawith and without notch. Also presents the effect of parameters ...

The Finite-Difference Time-Domain (FDTD) method is used to calculate the cellular phone far and near field and the specific absorption rate (SAR) in the user’s head. The conventional λ/4 monopole and a simple planar antenna are simulated and measured. The simulated results are in good agreement with those measured for the VSWR and for the radiation patterns on the horizontal and vertical planes...

Abstract – A Novel Co-Planar Wide Band Slot Antenna is proposed in this paper. In this paper a new design technique for enhancing bandwidth that improves the performance of a conventional microstrip patch antenna is proposed. This proposed antenna has been excited by probe feed technique. On a thin FR –4 lossy substrate this antenna achieves 1.87 GHz impedance bandwidth in the range of 2.24 4.1...

Proposed is a new simple technique for achieving band rejection characteristics in ultra-wideband monopole antennas. Two band notches were added to an existing UWB antenna by gluing a padding patch printed on a small single-layer piece of commercial substrate. The design of the new proposed structure has a controllable rejection in the 5 GHz WLAN and 8 GHz ITU frequencies while maintaining a wi...

The design and analysis of ellipse shaped broad band micro strip patch antenna are discussed in this paper. In modern wireless communication system at the higher frequency, this basically needs all its components to be in compact size. The proposed antenna inspired by ellipse shaped which offer the better performance compare to the conventional antenna. Here, the proposed antenna is one such co...

This paper presents a design of triangular wide slot antenna with same shaped patch which is fed by CPW. Patch is working as a radiating element and wide slot working as a ground. Detail simulation is conducted to understand its behaviour and optimize for broad band operation. The results are analysed and discussed in terms of return loss, VSWR, Gain, current distribution etc. The result shows ...

This paper introduces a novel feeding technique aimed for increasing the bandwidth of a patch antenna. It is shown that by using two 180 degrees out of phase excited cylindrical probes, the bandwidth of a patch antenna can be dramatically increased. Based on the proposed differential cylindrical probes (DCP) feed, we designed a square patch antenna with 104% impedance bandwidth for VSWR<2:1. Th...

MIMO antennas are a type of antennas using more than one antenna for transmission and reception of signals. The proposed 2x2 MIMO antenna having two antennas in that one antenna is horizontally polarized and another antenna is vertically polarized. The proposed antenna works on C band. The newly designed 2x2 MIMO system works on 5GHz with 250MHz-300MHz bandwidth with reduced VSWR and high gain....

In this paper a novel design of small sized, low profile coaxial fed microstrip patch antenna is proposed for terrestrial DTV signal reception applications in the UHF band frequency range of 540-890MHz. Designed model was spiral slot microstrip patch antenna using shorting plates for size reduction. Different parameters like return loss, VSWR, gain along θ, Ø directions, radiation pattern in 2D...
