This paper presents a design of a wideband array antenna consisting of a leaf-shaped bowtie slot antenna (LSBSA). A four-element LSBSA array is designed such that the array operates over the frequency band of 7–10GHz. In order to demonstrate the effective performance of the presented configuration, characteristics of the designed LSBSA array are evaluated by the finite-difference time domain (FDTD)...
The duopoly model of vendors in a linear open city is developed in order to analyze the equilibrium location of vendors in Stackelberg competition. It is shown that the equilibrium vendors' location is either clustered or dispersed? in the city depending on the relative sizes of shopping cost and commuting cost. It is furthermore shown that the equilibrium vendor location is socially inefficient....
The duopoly model of vendors on a linear open city is developed in order to analyze equilibrium location of vendors and city residents. It is shown that at the equilibrium vendors locate at either the city edge or city center, with positive distance each other. It is also shown that the equilibrium vendor location is too far from the city center and the city size is too large comparing to the total...
