Circular polarization (CP) radiation of the shorted ring‐slot antennas is achieved by selecting a proper length of the shorted section in the ring slot, which is about 3.9 and 8% of the mean circumference of annular and square ring slots, respectively, and feeding the ring slot using a microstrip line 90° to the shorted section. Pattern and Frequency Reconfigurable Annular Slot Antenna ... Annular slot antenna schematic The feeding line with the matching Fig. 2. Simulated normalized radiation patterns on the x-y plane with a short stubs are on the bottom and the annular slot antenna is on the top side of the circuit at 225 . The null direction for the slot without any short would be in the substrate. US9692137B2 - Annular slot antenna - Google Patents An annular slot antenna includes an inner conductor divided by a dielectric gap into a rear section and a front section. An inner conductor of a coaxial feed line is contacted with the front section of the inner conductor and the outer conductor of the coaxial feed line is contacted with the rear section.

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.
