35-GHz Wideband Vertical Off-Center-Fed Dipole and Its Array in LTCC Technology
A 35-GHz wideband low-temperature co-fired ceramic (LTCC) vertical off-center-fed dipole antenna and its 2×2 array are 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 di...

| description | A 35-GHz wideband low-temperature co-fired ceramic (LTCC) vertical off-center-fed dipole antenna and its 2×2 array are 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 mm3 exhibits a measured -10-dB |S11| bandwidth of 25.4% and a measured maximum gain of 4.4 dBi at 32 GHz. Then, a 2×2 array was designed. The array with a dimension of 15×25×0.94 mm3 exhibits a measured -10-dB |S11| bandwidth of 28.6% and a maximum gain of 10.37 dBi at 31 GHz with a fluctuation of 1.8 dB over 31 to 39 GHz frequency range. The radiation performances of the dipole antenna and its array were also measured. Good agreement is obtained between the simulations and measurements. |
