Effects of Square Patch Antenna With Cut-off Frequency v/s Length -Width Variation.

This paper covers aspects of micro strip antenna designs excited by waveguide. The First aspect is the analysis and design of square patch and the effect of lengthwidth variation on cut-off frequency. This variation is mentioned in table and compared with calculated data using formula. This paper also shows the migration from c-Band to x-Band with increase in length-width. This effect can be removed by using patch antenna with circular slot.
