Textbook in PDF format This book explores various designs of wideband and circularly polarized slot-cut microstrip antennas realized using artificial neural network (ANN) modelling approach. The ANN modelling has been employed in variety of application in wireless domain. In this book, ANNs tools are used for design and predicting the antenna behaviour as well as tailoring designs as per specific frequency requirements. The book presents various designs employing regular shapes like, rectangular, circular and modified compact shapes like, semi-circular. The neural network approach used in this book achieves accurate antenna designs for wide frequency range and substrate parameters, based on the intended application, thus demonstrating the effectiveness of predictive modelling in developing the wideband and circularly polarized antennas
