A design for a broadband single-layer dual-band reflectarray antenna is presented. A genetic algorithm is employed to design and optimize the element of the antenna. The basic idea to improve the bandwidth of the proposed antenna is based on increasing the range of the linear region of the phase response of the microstrip element.

Graphene ink used for printing RF antenna suitable for RFID ... Researchers at the University of Manchester, along with UK graphene manufacturer BGT Materials, printed a radio frequency antenna using compressed graphene ink.The antenna worked well enough to make it practical for use in radio-frequency identification (RFID) tags and wireless sensors, according to the researchers. DESIGN AND PERFORMANCE INVESTIGATION OF TUNABLE UWB THZ ... In this paper a tunable antenna using graphene-based fractal shape artificial magnetic conductor (AMC) is proposed for ultra-wideband (UWB) terahertz (THz) application. The resonance frequency of the proposed antenna can be tuned by varying the Electrically tunable mid-infrared antennas based on VO2 investigated based on the integration of optical antennas with tunable materials, such as photoconductive semi-conductors (10, 11), liquid crystals (12), phase-change materials (13–15), and two-dimensional materials such as graphene (16). Vanadium dioxide (VO 2) is a promising candidate for tunable optical devices. It exhibits a dramatic
