“…A dual band annular slot antenna has been proposed for GPS receiver in ref. [27] where dimension is 100 × 100 mm and bandwidth is 45 MHz on the lower band and 20 MHz on the upper band. On the contrary, we have achieved for the 1 st resonance at 1,11 GHz (16,14 GHz ÷ 15,03 GHz) bandwidth and for the 2nd resonce at 1,15 GHz (20,99 GHz ÷19,84 GHz) respectively.…”

Original scientific paper A microstrip antenna on Duroid 5870 substrate material has been presented for Ku and K-band applications in this paper. The proposed antenna has consisted of circular and rectangular slots printed on Duroid 5870 dielectric substrate material and excited by a 50 Ω microstrip transmission line. High frequency electromagnetic solver HFSS has been taken into account in this study based on the Finite Element Method (FEM). The antenna has generated two separate resonant frequencies to cover Ku and K-band. It has an impedance bandwidth (2:1 VSWR) of 1,11 GHz (16,14 ÷ 15,03 GHz) on the lower band and a bandwidth of 1,15 GHz (20,99 ÷ 19,84 GHz) on the upper band. It has achieved a stable omni-directional radiation pattern in the operating frequency band. The efficiency, current distribution, VSWR, return loss of the proposed antenna have been presented and discussed in detail.

“…However, the most disadvantage is that the complicated DC bias circuit must be carefully considered to compensate the inefficient feed structure for manipulating circular polarization [15,16]. Basically, the slot antenna embedded with a single probe feed structure can always create circular polarization [17][18][19], for instance, printing slot line at locations of 45 • and 135 • [20,21], adding stubs to couple with the excited orthogonal modes [22,23] etc. As embedded the PIN diode into the patch antenna to reconfigure the circularly polarized states was reported before [24][25][26], controlling the modes of PIN diode to adjust the surface current on radiator could be an alternative way to modify the polarization of the antenna.…”

Abstract-A functional microstrip circuit module for annular slot antenna is proposed. This module consists of an annular microstrip line component, two PIN diodes and a DC bias circuit. Reconfigurable circular polarizations can be simply controlled by this functional module. Axial ratio is adjustable by changing the clip angle of the notch made by the annular microstrip line component. Simulated and experimental results have shown good impedance bandwidth for return loss and antenna gains in circularly polarized states.

“…It was shown in the literature that a large number of sources (or antennas) making it possible to generate a circular polarization and capable of exciting the EBG antenna. Among these we can find the printed antenna [1]- [9] (or more commonly called patch antenna), the helical antenna, the slots [10] and fed cones [11] Waveguide and other 3D solutions. It should be noted that this list is not exhaustive and can be completed.…”

Abstract-The work on this guideline focus on the development and the design of a circularly polarized metallic EBG antenna fed by two microstrip lines. In order to achieve that purpose, a list of indicative specifications has been established, namely, obtaining an antenna operating from 29.5 to 30 GHz, with a high gain value, an ellipticity rate less than 3 dB and a secondary lobes less than -12 dB which is designed for Radio Frequency Identification (
