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 A Circularly Polarized Annular-ring Patch Antenna with a ... a circularly polarized annular-ring patch antenna embedded in a particular EBG structure and with an unequal cross-slot in the ground plane is studied and presented. This recently proposed annular-ring antenna structure has been shown to be significantly smaller than conventional annular-ring patch antennas, even on standard groundplanes [10].

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.
