Abstract

The field distribution between strips in a periodic array of parallel strips was modeled. The electric field integral equation (EFIE) together with method of moments was employed to solve the problem. The incident plane wave was assumed to be transverse magnetic (TM) and transverse electric (TE). The effect of the incident angle on the field between strips was investigated. For comparison, an array of the same configuration but containing a finite number of parallel strips was also modeled using the EFIE and solved via the method of moments. Good agreement between the results from the periodic array and the finite array was found even when the number of strips is small. It is also found that the presence of the ground plane does not have much effect on the field distribution, but only raises the field strength level when the observer is located below the top of the parallel strips. The results are of interest for cellular mobile radio community in predicting the range dependence of a signal from a base station antenna, when propagating in built up residential area.
