In this letter, a broadband, low-profile, hybrid water antenna is proposed. The hybrid structure combines the resonance of the dielectric resonator (DR) and the resonance of the monopole together to cover the required frequency band. The unique features of the water DR are transparency, reconfigurability, and liquidity, which allows complex structures (including the antenna feeding line) to be placed...
A broadband circularly polarized (CP) cross-dipole antenna is proposed for GNSS applications. The antenna has a very simple structure and a small size but has a very broad impedance bandwidth from 1.15 to 1.75 GHz (a fractional bandwidth of 41.4%) for S11 < −10 dB. The CP bandwidth is from 1.37 to 1.5 GHz for axial ratio < 3 dB. A computer simulation is conducted to optimize its dimensions and...
In this paper, a low profile, broadband, dielectric resonant antenna (DRA) with a U-shaped water layer is presented for DVB-H (470 – 862 MHz) mobile applications. The U-shaped water layer is used as a radiator to reduce the antenna size. The proposed antenna has a −6 dB impedance bandwidth from 461 to 1019 MHz, or a fractional bandwidth of 75%, and about 1.5 dBi gain covering the whole DVB-H band...
