  • Comparison between a novel liquid switch and a GaAs MMIC switch for reconfiguring the operating frequency of a Vivaldi antenna
    Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Wong, Kai-Kit (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    This article proposes a novel liquid switch to reconfigure the operating frequency of a frequency-independent antenna. A Vivaldi antenna using a low-cost GaAs MMIC RF switch is used as a landmark to compare the measured ...
  • High-gain frequency reconfigurable Vivaldi antenna
    Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Benton, David M. (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This article proposes a frequency agile antenna whose operating frequency band can be switched. The design is based on a Vivaldi antenna. High-performance radio-frequency microelectromechanical system (RF-MEMS) switches ...
  • High-gain triple-band reconfigurable Vivaldi antenna
    Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Brittan, P. (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    A frequency agile Vivaldi antenna whose operating frequency band can be switched is pro- posed. High-performance radio-frequency micro- electromechanical system (RF-MEMS) switches al- low tuning of the operational band ...
  • Low cost 3D-printed monopole fluid antenna
    Tong, Kin-Fai; Borda Fortuny, Cristina; Bai, Jingyi (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Low cost 3D printed monopole fluid antenna is investigated. The PDMS container of the seawater is fabricated by 3D printing technology for reducing cost and complexity. The design parameters of the antenna have been studied ...
  • Reconfigurable antennas for very wide spectrum monitoring
    Amiri, Amin; Borda Fortuny, Cristina; Tong, Kin-Fai (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Two different reconfigurable techniques for spectrum-monitoring antenna are presented. The first method inserts high-performance RF-MEMS switches along the microstrip feed line and back slot of a Vivaldi antenna for switching ...
