“…A structure of the asymmetrical ground plane in [5] was used to excite a CP operation at 1.57 GHz with the width of the CPW ground plane adjusted simply. As reported in [6], a CP operation was introduced by two arms with different lengths in a simple printed monopole. In addition, with using slots in the ground [7], four notch slots [8], feed positioning with U-and E-shaped slots [9], slotted monopole [10], S-shaped slots [11], inverted L-slits on the ground and feed networks composed of three Wilkinson power dividers [12] included, a great effort was revealed in implementing various techniques for obtaining circularly polarized monopole antennas.…”

Abstract-A novel broadband circularly polarized planar monopole antenna fed by coplanar waveguide (CPW) is proposed and fabricated. The proposed antenna consists of a rectangular monopole, an inverted-L strip and an asymmetric ground plane with cutting a horizontal slit on the right ground plane. Firstly, a narrow circularly polarized (CP) radiation at the upper band can be achieved by utilizing the asymmetric ground plane. Then, an inverted-L strip is introduced to obtain broadband CP characteristic matched with wide impedance bandwidth. The measured results demonstrate that a 10-dB bandwidth of 58.8% from 4.8 to 8.8 GHz and a 3-dB axial-ratio bandwidth (ARBW) of 47.8% from 5.375 to 8.75 GHz can be achieved which can completely cover the WLAN (5.725-5.85 GHz) band. Additionally, a 10-dB impedance bandwidth of 24% (3.3-4.2 GHz) with linear polarization is also obtained which can completely cover the WiMAX (3.3-3.7 GHz) bands. In additional, to explain the mechanism of dual-band CP operation, the analysis of magnetic fields distributions and a parametric study of the design are given. Compared to other recent works, a simpler structure, wider axial ratio and impedance bandwidths and a more compact size are the key features of the proposed antenna.

“…Many applications having a need of multiband linear and circular polarizations performance within a single antenna [2]. Mostly networks such as WLAN used circular polarization (CP) to improve the polarization effectiveness of link budget [3]. Two semicircle on the base edge of the ground plane and two bevel slots on the upper edge [4] and using a half -bowtie radiation patch with staircase shape [5] are also used for the bandwidth enhancement.…”

A compact monopole antenna having wide bandwidth with multi-bands as well as dual polarization characteristics for wireless communication is presented. To get impedance matching for the SMA conductor, the antenna is fed up by Micro-strip feeding technique. In this, the antenna is embedded by an L-shaped slots on the ground plane, to improve the bandwidth by excited the addition of resonance. To generate the multiband characteristic, with dual polarization, the inverted E-shaped parasitic structured as a replacement is used in the back of the substrate and upper side of the ground. The measured results show that the proposed dual polarized monopole antenna offers a very high gain 7 dB with 10 dB return loss with multi notched bands, covering all the (3.18-3.66) GHz Wi-MAX, (5.18-6.22) GHz WLAN, (6.89-9.07) GHz X bands.

“…A coplanar waveguide (CPW)-fed monopole antenna with a shorting sleeve strip was used to excite a CP mode by the coupling effect between the monopole antenna and sleeve [9]. In addition, a printed CP omnidirectional Yshaped monopole antenna was also presented in [10]. However, the CP monopole antennas mentioned above are focused on the singleband operation and the radiated fields of these previous designs are RHCP or LHCP.…”

Abstract-A novel loop-like monopole antenna with dual-band circular polarization (CP) for the reception of WiMAX and WLAN is designed and implemented in this paper. The antenna consists of a radiating patch which is composed of an annular-ring linked by a square ring over the corner and a ground plane with embedded rectangular slit. The broad impedance bandwidth is achieved based on a novel monopole structure which is the combination of two perturbed loops and the perturbation causes the generation of right-hand circular polarization (RHCP) at 3.52 GHz and left-hand circular polarization (LHCP) at 5.75 GHz. In addition, by embedding a rectangular slit on the ground, the impedance bandwidth can be greatly enhanced. The measured results show that the proposed monopole antenna has an impedance bandwidth of 3.65 GHz from 2.65 to 6.3 GHz, reaching the particularly broad bandwidth of 81.6%. Furthermore, the measured 3-dB axial ratio (AR) bandwidths are about 440 MHz at the lower band (3.52 GHz) and 220 MHz at the upper band (5.75 GHz). The radiation characteristics of the implemented antenna are also presented.
