A Novel Concentric Annular-Ring Slot Dual-Band Circularly ... 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 ... A Novel Concentric Annular-Ring Slot Dual-Band Circularly ... In this paper, a novel concentric annular-ring slot dual-band CP microstrip antenna that operates at ISM band (2.45GHz) and 5G band (3.5GHz) is proposed and investi-gated. 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.

The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, designed on the bottom of the Duroid substrate. The
In recent studies, concentric annular rings have been used for designing dual band antenna, where a second ring was placed within thefirstring,each operatingintheTM12 mode[10,11]and[12]. In[12], the impedance properties of a dual frequency concentric annular ring microstrip patch antenna are described. This patch operates at two Effect of the Different Shapes: Aperture Coupled Microstrip ... Effect of the Different Shapes: Aperture Coupled Microstrip Slot Antenna 105 Microstrip Feed Line Feed substrate dielectric constant should be in the range of 2 to 10.A thinner feed substrate results in less spurious radiation from feed lines, but higher loss. A compromise of 0.01 λ to 0.02 λ is usually good. Loaded annular ring slot microstrip antenna for wideband and ... In this article, an annular ring slot microstrip antenna loaded with two pie-shaped circular sectors is presented. With the use of pie-shaped circular sectors along the microstrip feed line, a multi-wider-band operation than for a conventional annular ring slot can be realized.
A wideband orthogonally slot cut annular ring microstrip antenna fed by L-shaped probe is investigated using modal expansion cavity model and circuit theory approach. Simulation of the proposed antenna is performed using Ansoft HFSS and simulated results are compared with the...

Aperture-coupled microstrip line fed annular-ring patch antennas, have also been shown to produce circular polarization. [10]. In this paper, two enhancement techniques are applied to the circularly polarized annular-ring patch antenna; embedding strips in the annular ring and cutting a crossed-slot into the ground plane.
