“…In circularly-polarized (CP) designs, both of these approaches can be utilized by acting on the scattered phase of each polarization independently. There also exists a third option for CP designs, whereby the element can be physically rotated to directly manipulate the phase shift [9] [10].…”

“…This was proposed as early as the 1970's by integrating diodes in a rotation-invariant geometry [73], so that selectively actuating some of the lumped elements implements the 'electromagnetic rotation' of the element. An example is illustrated in Figure 5(a), where the rotation of a dipole is implemented [38] by switching the desired pairs of branches (slots [10] and metal split rings [74] have also been used). Figure 5(b) shows a full array implementation of the concept.…”

Abstract-Advances in reflectarrays and array lenses with electronic beam-forming capabilities are enabling a host of new possibilities for these high-performance, low-cost antenna architectures. This paper reviews enabling technologies and topologies of reconfigurable reflectarray and array lens designs, and surveys a range of experimental implementations and achievements that have been made in this area in recent years. The paper describes the fundamental design approaches employed in realizing reconfigurable designs, and explores advanced capabilities of these nascent architectures, such as multi-band operation, polarization manipulation, frequency agility, and amplification. Finally, the paper concludes by discussing future challenges and possibilities for these antennas.

“…Various methods have been introduced for synthesis of FBRAs microstrip elements, such as: With elements of the same shape and size which are loaded with stubs of different size [4], with elements of the same shape but different lengths [5], with elements of the same shape having slots of different size on the patch [6], with elements of the same shape and slots of different size on the ground plane [7], with loaded elements that their rotation angle is changed with stubs of circular polarization [8], with slot ring resonator elements [9], with ring resonator elements [10], with folded reflectarray elements [11], . .…”

Abstract-In this paper, a wideband microstrip antenna for Xband (8.2 GHz-12.4 GHz) applications is introduced. First, simple patch antennas are studied, and a narrowband reflectarray antenna is designed. The resultant design demonstrates better performance than the previously published narrowband microstrip reflectarray antennas. The important features of the employed elements are simple structure, linear operation, and use of Radio Frequency Micro Electro Mechanical Systems (RF MEMS) switches for programmable pattern control. Next, employing our novel method, the designed narrowband structure is converted to broadband reflectarray antenna that can cover the whole X band. This novel idea is based on introducing several ground plane slots and controlling their electrical lengths by RF MEMS switches. By means of this method, 952 and 587 degree phase swing are achieved for continuous and discrete slot length variations, respectively. Application of this method along with smaller switches results in phase swing improvement of up to 1616 degree. In all structures a RT duroid (5880) substrate is selected to lower the back radiation. The achieved return loss in all cases is less than 0.32 dB. In comparison with the previous publications, our novel bandwidth enhancement technique has more generalization capability and results in single layered broadband reconfigurable microstrip reflectarray antennas with linear phase swing, lower cost, and ease of RF MEMS implementation.

“…The basic cells consist of a ring resonator -RR (Ring Resonator) or CLL (Capacitively Loaded Loop) in SRR (Split Ring resonator) or CSRR (Complementary Split Ring Resonator), fractal cells and Jerusalem-Cross-Pair topologies. Furthermore, periodic structures such as Ring Slot Resonators can be considered as reconfigurable antennas when properly loaded [15].…”

Abstract:In this work it is shown the strategy of use metamaterial technology to improve the GTEM chamber performance.The analysis and characterization of different types of metamaterial patterns, such as fractal cells, Jerusalem-Cross-Pair, SRR -Split Ring Resonator and CSRR -Complementary Split Ring Resonator printed on the septum of a GTEM chamber was done. The main goal is to give a flexibility frequency range for electromagnetic compatibility analysis of integrated circuits and electronic boards. Experimental results are compared to simulated ones showing the advantages of the tuned characteristic of the patterned septum in comparison to the conventional type. This technique appears as an option for the performance optimizations of compact GTEM chambers.
