A stepped impedance comb-line filter fabricated by using ceramic lamination technique

Structures and dielectric properties of a new dielectric material system xMgTiO3–(1−x)MgTa2O6 at microwave frequency

“…Requirements for these dielectric resonators include a high dielectric constant (ε r ) for possible size miniaturization, a high quality factor value (Q × f) for frequency selectivity and low signal attenuation and a near zero temperature coefficient of resonant frequency (τ f ) [1,2]. To satisfy the demands of microwave circuit design, each dielectric property requires intimate control.…”

The control of electrical properties of multilayered LC-filter for 5 GHz applications

“…However, the roll-off of laminated LC filter is not so good in comparison with other filters such as dielectric filter, SAW and F-BAW filter. Thus, many researches and developments [1][2][3][4] have been performed in order to improve the filter characteristics. With the rapid increase of the amount of data transfer, application frequency band expands to the higher frequency region for wireless communication systems.…”

Compact 5.8-GHz bandpass filter using stepped-impedance dielectric resonators for ISM band wireless communication

“…A very small dielectric bandpass filter was fabricated with the introduction of the ceramics lamination technique [9]. Furthermore, a miniaturized two-stage bandpass filter in a combline configuration using the same technique was also reported [10,11]. However, they still possess higher loss than that of ceramic filters, especially at higher frequency region.…”
