Abstract

In this paper, a circular microstrip patchcentrally etched with a cross slot is studied. The slot dimensions are varied for controlling the reflection lossand thephase range of a reflectarray. It is found that the dominant TM mode of the slotted circular patch can be easily excited, and the slot length can be varied to function as a phase-changing parameter. Cross slots with equal and unequal arms are investigated. Study shows that the slope of the S curve can be made slow-changing by increasing the slot width. A maximum reflection phase range of 328.68º is achievable in the S curve. Rectangular waveguide method has been deployedfor simulating and verifying the design idea. Reasonable agreement is found between the measurement and simulation.
