Radiation Pattern Agile Antenna using PIN Diodes and SPDT Switches

[EN] In this paper, a new design of a reconfigurable antenna is proposed. The antenna structure is using two PIN diodes for switching between two radiation patterns (directional and bidirectional) and a SPDT switch to achieve good impedance matching. The simulated results show a good impedance matching, with S11 below -10 dB using the SPDT switch configuration. In addition, the far-field directivity for both configurations is around 5 dB.Zakaria, M.; Antonino Daviu, E.; Ferrando Bataller, M. (2020).
