Effect of Lossy Earth on Antenna Gain

چکیده
The effect of lossy earth on the far fi eld gain of antennas with finite s ize metal ground planes has been investigated experimen tally. Gain measurements were made of several antennas and their associated ground planes mounted both flu sh with the surface o f the ear th and far removed from the earth. It was found that for the ground plane sizes used in this study the gains for the two situations d ifIered only at low elevation angles. T he results suggest that on e may estimate the behavior of an antenna over conducting ea r th by mcasuring the free space gain u t il izin g simple modeli ng techniqucs on a conventional antenna pattern ran ge.

A Miniaturized CPW-Fed Tapered Slot Antenna in Lossy Environment for UWB Application in Breast Cancer Detection
In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition) a...
متن کاملA Study of Electromagnetic Radiation from Monopole Antennas on Spherical-Lossy Earth Using the Finite-Difference Time-Domain Method
Radiation from monopole antennas on spherical-lossy earth is analyzed by the finitedifference time-domain (FDTD) method in spherical coordinates. A novel generalized perfectly matched layer (PML) has been developed for the truncation of the lossy soil. For having an accurate modeling with less memory requirements, an efficient "non-uniform" mesh generation scheme is used. Also in each time step...

A theore tical analysis is made of the effect of antenna s ize on parameters such as gain, bandwidth, and efficiency . Both near-zone and far-zon e direct ive gains are considered . It is found that t he maximum gain obtainable from a broad-band antenna is approxima tely equal t o that of the uniformly illumina ted aper t ure. If higher gain is desired , the antenna mus t necessarily be a narro...

In this article an Archimedean spiral antenna is designed and analyzed that has good operation in broadband application. By analyzing this design, the effects that different parameters have on antenna operation will be studied and ways of optimization will be found. Influences of cavity height and number of turns to obtain good matching and gain in a frequency interval of 4 to 18 GHz will be d...
متن کاملPerformance Enhancement of Wearable Antenna Using High Impedance Surfaces
This paper presents a novel textile wearable antenna that has been designed to operate at Wi-Fi bands of 2.4GHz & 5.8GHz. Antenna performance in free space environment showed Gain of 1.8dBi at 2.4GHz and 4.5dBi at 5.8GHz. However, performance deteriorated when antenna was operated near human body which is lossy and complex in nature. For mitigating the human body effect on antenna performance, ...
