title = "Reconfigurable Metasurface with a Novel Coupled Line Structure for Ka-Band",
abstract = "A reconfigurable 4x4 metasurface structure for Kaband is proposed. The reconfigurability is achieved with the control of varactors and PIN diodes which enable electrical beam steering and polarization control respectively. Moreover, a novel coupled line structure is employed to eliminate lumped components, e.g. inductors and resistors, which are typically used to bias the above-mentioned components. The novel structure provides a ground connection while having high coupling which ensures robust performance at the operation frequency of 28 GHz. To demonstrate the operation, simulation results of the 4x4 structure are presented at 0° and ± 30° steering angles with a gain of 11.2 dB and 4.5/4.4 dB respectively. The cross-polarization discrimination levels for vertical and horizontal polarization are -20.0 dB and -22.8 dB respectively.",
