radiation characteristics of plasma triangular antenna
this paper presents the results of a study on the radiation characteristics of a plasma triangular antenna in the vhf band (30-300mhz) applying the method of moment. deriving the current distribution of the antenna, it shows the relationship between radiation characteristics of the plasma antenna and the plasma parameters. both theoretical and numerical results indicate that if the plasma frequ...
متن کاملTheoretical Study of Radiation Characteristics of Short Dipole Antenna
This paper theoretically examines the key dipole antenna parameters that define their performances in terms of current distribution, radiation resistance, input impedance, radiation efficiency, size, bandwidth, quality factor and directivity. We have investigated how these parameters are related to each other and also how variation of one alters the overall performance of the antenna. Bandwidth...
متن کاملImpedance of a Short Dipole Antenna in a Cold Plasma
This paper presents the analysis of the impedance of a short dipole antenna in a cold plasma using a quasi-static approach. Two radically different current distributions on the antenna are considered and their influences on the antenna impedance are studied. These distributions include a one-dimensional (1-D) triangular distribution and a three-dimensional (3-D) exponential current distribution...
متن کاملRadiation Characteristics of a Plasma Column Antenna
By means of the study on electromagnetic (EM) waves propagating along the plasma column, it is found that the radiation of a plasma column is caused by two kinds of operation modes. The first one is a guided mode which leads to a surface current radiation, and its operation condition is obtained by boundary conditions and physical properties of plasma. The second one is a leaky mode which resul...
متن کاملA New Design of Log-Periodic Dipole Array (LPDA) Antenna
This paper presents a new approach for design of the log-periodic dipole array antenna (LPDA) based on using of different design parameters in the LPDA elements to control the antenna behavior. In the proposed procedure, the design parameters can control the value of forward gain over the operating frequency range, and also adjust the gain flatness. Furthermore, this design procedure can decrea...
