Dielectric properties of B2O3-doped (1 − x)LaAlO3–xSrTiO3 ceramic system at microwave frequency

Microwave dielectric properties of 0.95MgTiO3–0.05CaTiO3 for application in dielectric resonator antenna

“…The resonant frequency of the circular disk dielectric resonator antenna excited at the dominant TM110 mode is [1]: (2) where X 11 = 1.841 is the first zero of the equation J 1 (x) = 0 and c is the speed of light in a vacuum. One advantage of the dielectric resonator is ease of excitation.…”

“…The dielectric resonator antenna offers very high radiation efficiency due to its low dielectric loss and it has no metallic loss. A near-zero temperature coefficient of resonant frequency is for high temperature stability [2,3]. is well known as dielectric resonators and filters [4,5].…”

Low-temperature sintering-microwave dielectric property relations in Ba3(VO4)2 ceramic

“…In the case of LTCC technology, the dielectric are needed to co-fire with electrode metal with high conductivity such as silver, depending on the requirement of the small delay time of the signal and low power consumption; therefore, the sintering temperature of the dielectrics should be lower than the melting point of silver. It is generally known that liquid phase sintering by the additions of sintering aid such as B 2 O 3 , V 2 O 5 , and CuO [1][2][3] is effective in reducing the sintering temperature of microwave dielectric ceramics, though * Corresponding author.…”

Microwave dielectric properties of Mg3(VO4)2–xBa3(VO4)2 ceramics for LTCC with near zero temperature coefficient of resonant frequency

“…In the case of a LTCC, however, the sintering temperature of these ceramics is still too high to use silver as an electrode material and the sintering temperature of the ceramics must be lower than the melting point of silver. It was reported that the addition of sintering aids such as V 2 O 5 , CuO, Li 2 CO 3 , and K 2 CO 3 was effective in lowering the sintering temperature of microwave dielectric ceramics; [8][9][10][11] therefore, the Li 2 CO 3 addition into the Mg 3 (VO 4 ) 2 -0.5Ba 3 (VO 4 ) 2 ceramics was also performed to lower the sintering temperature.…”
