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.

But all these designs in [13{15] have a limited range of the frequency ratio. In this paper, a novel dual-broadband circularly polarized antenna using two special slots and single microstrip-coupled feed is introduced and investigated.

Keywords: broadband antenna, pattern diversity antenna, slot antenna and ultra wide band (UWB) antenna.These microstrip lines generate orthogonal radiation patterns. In annular slot four shorts are placed between the microstrip lines to maintain isolation more than 25dB. 3.4.2 Multi-port annular ring slot antenna (M-ARSA) The annular ring slot antenna is a broadband antenna very suitable for the incoming wireless communication applications.This antenna, when excited on its fundamental mode, provides an omnidirectional radiation pattern. The slot-ring antenna is one class of radiating structures formed... A Reconfigurable Radiation Pattern Annular Slot
controlled radiation patterns. The Annular Slot Antenna (ASA) proposed in this paper operates at 5.8 GHz and the use of pin diodes along the slot circumference allows the radiation pattern to be directed in a number of different directions while the operation frequency remains constant. It is fabricated on SINGLE-FEED CIRCULARLY POLARIZED ANNULAR SLOT ANTENNA FOR ... Abstract|A novel dual-broadband circularly polarized folded slot antenna with single-feed is presented. The proposed antenna consists of two folded annular slots. By adjusting the asymmetric widths of the two slots, circularly polarized radiation can be achieved in two difierent bands. By optimizing the parameters of the proposed antenna, two Dual-band-notched antenna for UWB MIMO applications ...
