A broadband eccentric annular slot antenna
Broadband Circularly Polarized Annular-Ring Microstrip
A simple structure concentric annular-ring slot dual-band circularly polarized (CP) microstrip antenna operating at ISM band (2.45 GHz) and 5G band (3.5 GHz) is proposed in this paper. The antenna achieves dual-band operation by digging two concentric annular-ring slots on the ground. And on the angular positions with 45 degrees inclined of each annular slot, two bent structures are loaded to ... Eccentric Annular Slot Antenna for Breast Cancer Detection ... the wideband eccentric annular slot antenna to analyze and investigate the characteristics of malignant breast tumors. A FDTD based model is implemented to include the normal breast tissue, breast skin, malignant tumor and the transmitting/receiving antenna [1, 3-8]. The geometry of the antenna is shown in Fig. 1. This investigation will help in Broadband Annular Ring Microstrip Antennas | Products ...
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.

2019-5-17 · In this paper, an antenna comprising a compact annular-slot combined with a small concentric annular split-ring slot is presented. The antenna is fed by a T-shaped microstrip line. By using the T-shaped microstrip feedline to tune the level of electromagnetic coupling between annular-slot and feedline, good matching can be achieved.
