MICROSTRIP SQUARE RING ANTENNA FOR DUAL- BAND OPERATION S ... 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.

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.
