## 1 Introduction  
Space-fed electronically reconfigurable transmitarray antennas (SERTA) are in great demand due to their distinct features, such as a high gain, a low profile, a low cost, built structures, and feed options. These SERTA pictorial characteristics have attracted many researchers in the last few decades due to their wide applications in beam-forming and beam-scanning areas [1; 2; 3; 4; 5]. It includes satellite communication (SATCOM), civil and military radar systems, and 5G/6G communication systems for mobile access points [6]. Phase array architectures are typically heavy and bulky, making them unsuitable for various applications. Researchers have recently focused more on low-profile and compact designs. Much work has been conducted to achieve these characteristics in space-fed electronically reconfigurable memunitarray antennas for feed optimization and a compressed focal distance [7]. Most of the space-fed transmitarrays are not reconfigurable [8; 9; 10]. Reconfigurable technology is realized with the mechanical spinning of the systems, e.g., a motor. This method is still used nowadays due to its cost-effective waterproof behavior and ease of fabrication. On the other hand, this approach is unsuitable due to the bulky system design, mechanical vibrations, and higher latencies. The development of electronic components and miniaturization at higher frequency bands open new ways for the researcher to implement and design electronically reconfigurable beam-scanning and beam-forming arrays. These components are also helpful for implementing the transmitter (Tx)/receiver (Rx) modules. There are several reconfigurable components available to acquire beam-scanning and beam-forming operations, such as PIN diodes [11; 12; 13; 14; 15], varactor diodes [16], RF-electromechanical systems [17], liquid crystal and micro-fluids, etc. Each component has its pros and cons according to application requirements. There are multiple techniques reported in the literature, such as the multilayer frequency selective surface (MSFF) [18], material transformation approach [19; 20; 21], and transmitter-receiver method [22; 23], to design a transmitarray. The global demands for high data rates are rising day by day, and several applications of communication systems are driving researchers toward seeking a solution to address the high demand for data rates and higher bandwidth. Some efforts are utilized to design the high-bandwidth reconfigurable transmitarrays in the literature. A one-bit reconfigurable transmitarray is reported with varactor diodes placed on the microstrip patch antenna having 1 GHz bandwidth attained in a unit cell. Still, insertion losses are high due to the high insertion losses of varactor diodes [24]. A rectangle O-shaped slot transmitarray unit cell was designed with two diodes; however, the bandwidth of the unit cell was obtained at 14.1% [25]. A design with wide beam scanning and high bandwidth was presented with a high profile and a complex structure. In another work, a linearly polarized transmitarray for the Ku band was proposed using two orthogonal H-shape slots. The presented design has a 3 dB measured gain bandwidth of 9.6% [26]. This paper proposes a low profile and wideband electronically reconfigurable transmitarray at Ku band, essential in detecting drone strike technology (KuRFS) and radar and satellite communications. The bandwidth of most electronically reconfigurable transmitarrays (ERTA) is insufficient compared to the previously used phased arrays. Some of the disadvantages of ERTA in the literature include a significant gain scan loss and narrow bandwidth. Therefore, enhancing the ERTA's beam-scanning capability is essential to decrease the gain scan loss and increase the bandwidth. This research proposes a wideband meander-lines, one-bit electronically reconfigurable transmitarray at Ku band with linear polarization. The proposed unit cell works on polarization selection, and the polarization rotation is based on the symmetric current reversal phenomenon.
