A Method to Realize the Dual-Band Antenna With Independent Control and Flexible Frequency Ratios Based on Metasurface
The existing dual-band high-gain antennas based on metasurface have a common limit that the frequency ratios cannot be flexibly designated while the dual-band performances cannot be controlled independently. Here, a method to solve this problem is proposed; it adopts the concept of hybridizing a folded reflectarray and a Fabry–Pérot cavity antenna for high-gain dual-band operations. Different from previous works, the two antennas share a common aperture but are separated structurally by a polarization-selective surface that enables dual-band independent control and flexible frequency ratios. A prototype antenna is thus developed and experimentally examined, and the measured results agree well with expectations.
期刊介绍:
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
