The structure and applications of microstrip antennas are explained in this profound book. This book presents fundamental and enhanced theories of microstrip antennas comprising of design process and current functions. It discusses arrays, spectral domain, high Tc superconducting microstrip antennas, optimization, multiband, double and spherical polarization, microstrip to waveguide transitions and developing bandwidth and quality occurrence. Antenna fusion substance, microstrip circuits, spectral domain and efficiency are another few additional topics covered in this book. Planar UWB antennas have been extensively discussed. Plan of UWB antennas with solitary or multi notch bands has also been measured. This book intends to guide students and experts as well as those interested in dealing with microstrip antennas.
