Year: 2018

A 35-GHz wideband low-temperature co-fired ceramic (LTCC) vertical off-center-fed dipole antenna is presented. The widened bandwidth of the dipole antenna is achieved by paralleling a ring-shaped stub placed above the ground with a vertical off-center-fed dipole. The fabricated dipole antenna with a dimension of 7.5 19 0.94 mm 3 exhibits a measured -10-dB S 11 bandwidth of 25.4% covering the frequency range of 31.2 to 40 GHz and a measured maximum gain of 4.4 dBi at 32 GHz with a fluctuation of
