Abstract-This paper proposes a rectifying antenna (rectenna) for operation in the ISM (Industrial, Scientific and Medical) band centered at 2.45 GHz. It consists of a modified circular monopole loaded with a rectangular ring and a half-wave rectifier. Numerical and experimental data are reported and discussed. From measurements, it is demonstrated that when the power density incident on the monopole is 155 µW/cm 2 , the device here presented exhibits values of the RFto-DC conversion efficiency higher than 30% in the frequency range 2.35-2.5 GHz with a maximum of about 50% at 2.45 GHz.

“…but when the propagation of the higher order mode happens at the apertures of the antenna, 2 nulls are added to the radiation pattern. Furthermore, by attention to Equations (6) and (7), the proposed antenna has low cross-polarized radiation in both of the fundamental and higher order modes excitation, whereas most antennas exhibit high cross-polarized radiation at higher-order modes excitation. …”

“…Reconfigurable antennas can satisfy three groups of application requirements: resonant frequency [1], polarization [2,3], and pattern reconfigurability [4][5][6]. The pattern reconfigurability is one of the most effective methods to improve the performance of a wireless communication system by minimizing interference between users and maximizing signal-to-noise ratio (SNR).…”

Abstract-In this article, a novel compact reconfigurable antenna based on substrate integrated waveguide (SIW) technology is introduced. The geometry of the proposed antennas is symmetric with respect to the horizontal center line. The electrical shape of the antenna is composed of double H-plane SIW based horn antennas and radio frequency micro electro mechanical system (RF-MEMS) actuators. The RF-MEMS actuators are integrated in the planar structure of the antenna for reconfiguring the radiation pattern by adding nulls to the pattern. The proper activation/deactivation of the switches alters the modes distributed in the structure and changes the radiation pattern. When different combinations of switches are on or off, the radiation patterns have 2, 4, 6, 8, . . . nulls with nearly similar operating frequencies. The attained peak gain of the proposed antenna is higher than 5 dB at any point on the far field radiation pattern except at the null positions. The design procedure and closed form formulation are provided for analytical determination of the antenna parameters. Moreover, the designed antenna with an overall dimensions of only 63.6 × 50 mm 2 is fabricated and excited through standard SMA connector and compared with the simulated results. The measured results show that the antenna can clearly alters its beams using the switching components. The proposed antenna retains advantages of low cost, low cross-polarized radiation, and easy integration of configuration.

“…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. In this study, with improving the operational convention of the circular polarization for the annular slot antenna, we propose a more effective design for reconfiguring circularly polarized states by using a single probe feed structure with a functional module.…”

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.
