✦ Synopsis
A compact CPW-fed aperture-coupled patch antenna is modeled using the moment method code IE3D. It is shown that impro¨ements can be made by optimizing ¨arious parameters of the antenna, such as patch diameter, CPW slot width, etc. The impro¨ements are an increase in the bandwidth of the antenna, in the return loss across the band, as well as in the design which yield a more practical antenna in ( terms of construction i.e., typical manufacturing tolerances do not ) significantly affect the performance of the antenna . It is also shown that a CPW-fed aperture-coupled patch antenna can be made with a ground plane which will actually impro¨e the performance of the antenna after careful consideration of the height abo¨e the ground plane and dielectric used.
