Compact and Broadband Microstrip Antennas - twanclik.free.fr The microstrip antenna designs covered in this book are divided into two groups: compact microstrip antennas and broadband microstrip antennas. The book is organized into nine chapters. Chapter 1 presents an introduction and overview of recent advances in the design of both compact and broadband microstrip antennas. Annular Slot Loaded High-Impedance Ground Plane - ECE/CIS loop antenna over an annular slot loaded ground plane are shown in Section III. Section IV presents a parametric analysis of the ground plane’s effect using a numerically simulated broadband spiral antenna, including parametric analysis of the slot ring radius, slot width, substrate height, and substrate material.

A Cavity-Backed Broadband Circularly Polarized Slot/Strip A cavity-backed slot/strip loop antenna is proposed for a broadband CP operation. The slot/strip loop is a combination of a slot loop and a strip loop. The slot loop radiates a CP wave at a lower frequency while the strip loop produces CP radiation at a higher frequency. A combination of the two frequencies leads to a bandwidth enhancement.
