“…In [22], a circular LWA radiating a designable conical beam or broadside beam is proposed. Based on the structure, further research on the theoretical model for providing circularly polarized conical and broadside beam structures and a changeable beam structure have been developed [23,24]. The radiating elements on the upper surfaces of the antennas are handily fed by traveling wave structures.…”

Conformal antennas have been widely used in many fields due to their advantages of low air resistance and better visual appearance. In this paper, an arced conformal leaky-wave antenna (LWA) for a designable directional beam is proposed. The antenna is achieved based on a substrate-integrated waveguide (SIW). On the upper surface, a series of non-uniform transverse slots are etched. In order to guide the design of the antenna, as another key contribution of this work, a theoretical model for the traveling-wave structure is established. Using the model, the radiation property of the LWA is analyzed. In addition, by inputting the desired beam direction, the structural parameters of the LWA can be generated through the model. To verify the performance of the antenna and the model, an LWA prototype working at 28 GHz was fabricated and tested in a microwave anechoic chamber. The experimental results are in good agreement with the simulation results. The antenna achieved a gain of 9.96 dBi with cambered surface area of 1.89 λ02. The proposed method may be a promising candidate for conformal wireless communication applications.

Wireless mobile communication is one of the rapidly growing fields of Information and Communication Technologies (ICT). The adoption of smart antennas will also minimize the cost. The success of smart antennas relies on two phases: In first phase, the features of smart antennas should be considered in design phase of next-generation wireless mobile communication systems. In second phase, the performance of smart antennas should be analyzed according to crucial parameters that satisfy the requirements of next-generation wireless mobile communication systems. The proposed research study summarizes the concept and types of smart antennas. Further, the most recent innovations in smart antenna domains such as varying network conditions, coverage & connectivity, Quality of Service (QoS), energy efficiency, routing are discussed.
