The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. Annular Slot Antenna - How is Annular Slot Antenna In [12], dual-band circularly polarized annular slot antenna is obtained by employing two square slots, a bended microstrip line and a cavity back. As shown in Figure 2(a), antenna 1 is a fold annular slot antenna , and the asymmetric of the slot width will lead to two split orthogonal degenerate modes around 2.

Dual-frequency dual-sense circularly-polarized slot antenna fed by ... a microstrip feedline to the annular-slot. Microstrip-Fed Dual-Frequency Annular-Slot Microstrip-fed dual-frequency annular-slot antenna loaded by split-ring- slot.Abstract: A compact dual-band annular-slot antenna loaded by a concentric split- ring-slot is presented. A stepped microstrip feedline enables the control of the coupling and provides good matching.
Slot antennas are easier to make and modify, though patch antennas can be nearly as cheaply made using printed circuit board production lines. Slot antennas can send much more powerful signals. You can build a slot antenna into a structure and put it somewhere others may not know it is. The Pros and Cons of Slot Antennas

In this paper, a novel concentric annular-ring slot dual-band CP microstrip antenna that operates at ISM band (2.45 GHz) and 5G band (3.5 GHz) is proposed and investigated. The antenna is a kind of single-layer slot antenna. There are two concentric ring slots of different size on the ground to generate dual-band radiation.
