Bull’s-eye antenna with circular polarization at millimeter waves based on ridge gap waveguide technology
Pérez Quintana, Dayan
; Ederra Urzainqui, Íñigo ; Beruete Díaz, Miguel (IEEE, 2021)
Artículo / Artikulua 
In this communication, a Bull’s-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology is numerically and experimentally demonstrated. The structure is excited from the bottom with ... -
A millimeter-wave 4th-harmonic Schottky diode mixer with integrated local oscillator
Pérez Escudero, José Manuel ; Quemada Mayoral, Carlos ; Gonzalo García, Ramón ; Ederra Urzainqui, Íñigo (MDPI, 2021)
Artículo / Artikulua
In this paper the design and experimental validation of a fourth-harmonic mixer based on Schottky diodes working around 300 GHz is presented. The main novelty of this work consists in the integration of an MMIC-based local ... -
On the performance of the zoned fishnet metamaterial lens with positive and negative reference phase
Pacheco-Peña, Víctor ; Minin, Igor V.; Minin, Oleg V.; Beruete Díaz, Miguel (IEEE, 2016)
Artículo / Artikulua
In this letter, several converging fishnet metalenses are designed using both the zoning and reference phase techniques. They are engineered with a focal length of 1.5λ0 at the design frequency of 55 GHz (λ0 = 5.45 mm) at ... -
Ultrathin and high-efficiency Pancharatnam-Berry phase metalens for millimeter waves
Moreno-Peñarrubia, Alexia; Teniente Vallinas, Jorge ; Kuznetsov, Sergei A.; Orazbayev, Bakhtiyar ; Beruete Díaz, Miguel (AIP Publishing, 2021)
Artículo / Artikulua
Applying the Pancharatnam–Berry (PB) principle to half-wave plate (HWP) metasurfaces allows the manipulation of wavefronts along with the conversion of the handedness of circularly polarized incident waves by simply rotating ...
