Abstract: | A multiport network model for two-port rectangular microstrip patch antennas is introduced. This model is capable of accounting for the feedline-patch junction reactances as well as for the mutual coupling among the edges of the patch, and is used to evaluate two-port transmission characteristics of rectangular patches. The proposed model has been applied to the analysis of rectangular patches used as elements of series-fed microstrip arrays. Results presented show that it is possible to match a two-port patch at the input port and, at the same time, to achieve a specified transmission coefficient to the other port to taper the amplitude distribution of the array appropriately. These experimental results verify the validity of the proposed model and the method of analysis used |
