This book presents electromagnetic (EM) design and analysis of dipole antenna array over high
impedance substrate (HIS). HIS is a preferred substrate for low-profile antenna design  owing
to its unique boundary conditions. Such substrates permit radiating elements to be printed on
them without any disturbance in the radiation characteristics. Moreover HIS provides improved
impedance matching  enhanced bandwidth  and increased broadside directivity owing to total
reflection from the reactive surface and high input impedance. This book considers different
configurations of HIS for array design on planar and non-planar high-impedance surfaces.
Results are presented for cylindrical dipole  printed dipole  and folded dipole over single-
and double-layered square-patch-based HIS and dogbone-based HIS. The performance of antenna
arrays is analyzed in terms of performance parameters such as return loss and radiation
pattern. The design presented shows acceptable return loss and mainlobe gain of radiation
pattern. This book provides an insight to EM design and analysis of conformal arrays. This book
serves as an introduction for beginners in the design and analysis of HIS-based antenna arrays.
It includes pictorial description of both planar and non-planar array design and the detailed
discussion of the performance analysis of HIS-based planar and non-planar antenna array. It
will prove useful to researchers and professionals  alike.
