    Low-loss Circularly Polarized Periodic Leaky-Wave Antenna 
    Sánchez-Escuderos, Daniel; Ferrando Bataller, Miguel; Herranz Herruzo, José Ignacio; Rodrigo Peñarrocha, Vicent Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This letter presents a periodic leaky-wave array antenna with circular polarization at millimeter-wave frequencies. The antenna is designed on the low-loss planar Goubau transmission line to maximize the radiation efficiency ...

    Reconfigurable slot-array antenna with RF-MEMS 
    Sánchez Escuderos, Daniel; Ferrando Bataller, Miguel; Baquero Escudero, Mariano; Herranz Herruzo, José Ignacio (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Cylindrical near-field measurement systems are being widely demanded, especially for imaging applications at millimeter-wave frequencies. One of their most important drawbacks is the long time required to perform a full ...

    Untilted narrow-wall slots excited by parasitic dipoles in groove-gap waveguide technology 
    Herranz Herruzo, José Ignacio; Valero-Nogueira, Alejandro; Martínez Giner, Sara; Vila Jiménez, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2015-11)
    This work describes a new way to excite untilted slots in the narrow wall of a rectangular waveguide. The radiating structure consists of an inclined parasitic dipole located within the waveguide, parallel to narrow ...
