Analysis of Planar Microstrip Circuits Using Three-Dimensional Transmission Line Matrix Method
The frequency-dependent characteristics of microstrip planar circuits have been previously analyzed using several full-wave approaches. All those methods directly give characteristic of the circuits frequency by frequency. Computation time becomes important if these planar circuits have to be studied over a very large bandwidth. The transmission line matrix (TLM) method presented in this paper ...
متن کاملFundamental characteristics of a planar folded dipole antenna with a feed line on the dielectric substrate
Recently, the many services for the cellular phone are spread. Therefore, the broadband antenna for handsets is required. In our previous paper [1], the planar folded dipole antenna (PFDA) with a feed line, which consists of two parallel lines has been introduced and its characteristics have been analyzed. As a result, it was found that PFDA with a feed line had a broadband characteristic and t...
متن کاملMillimeter-Wave Microstrip Line to Waveguide Transition Fabricated on a Single Layer Dielectric Substrate
The millimeter-wave front-end module for an automotive radar sensor is generally composed of an antenna placed on the front surface of the sensor head and a millimeter-wave circuit inside it. As the antenna for the radar sensor, several types of antennas, a slotted waveguide antenna, a triplate antenna, a dielectric lens antenna, a dielectric leaky wave antenna and a microstrip antenna, have be...
متن کاملMicrocontroller Based Dielectric Constant Measurement
A dielectric constant measurement setup has been developed to measure dielectric constant of liquids using AT89C55WD microcontroller. A modified operational amplifier based AC Schering Bridge network is used to compute capacitance and hence calculate dielectric constant of liquids. This instrument system permits recording of dielectric constant of liquids at various concentrations and temperatu...
متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
