“…In other word, the resonance frequency is reduced below 600 GHz. It indicates that the behavior of the antenna can be changed to a slow-wave structure [38]. In a normal condition, to reduce the resonance frequency of the antenna, it is Fig.…”

In this paper, an effective permittivity of the twolayer dielectric substrate material has been analyzed to enhance the electrical performance of the rectangular microstrip patch antenna at terahertz frequency. The frequency dependent effective dielectric permittivity of the substrate materials has been evaluated and result has been compared with finite integral technique based CST Microwave Studio a commercially available simulator. The input impedance characteristic with electrical performance of the rectangular microstrip patch antenna on two-layer substrate materials has also been analyzed at 600 GHz. Manipulation in the input impedance characteristic of the antenna has led to a slow wave structure. This slow wave structure has been examined at 542 GHz, and improvement in the performance has been observed without increasing the overall dimension of the proposed antenna.

“…Lumped element filter design for this frequency range has been reported using low-temperature co-fired ceramic (LTCC) [6] or micromachining techniques [7]). MEMS technologies, including membrane suspended techniques, have been developed in the last years, with a lot of applications in manufacturing of circuits working in the microwave and millimeter wave frequency range [8][9][10][11][12][13][14][15][16]. The aim of this paper is to illustrate a new topology of a lumped element band pass filter with an improved high frequency band stop response.…”

This paper describes the design, manufacturing and experiments of a lumped element band pass filter in a new topology. The design starts from a second order capacitive coupled resonator topology. An additional series inductor is inserted in the filter classical topology, for shifting two transmission zeros on the real frequency axes in the filter's band stop, to improve the high frequency response. Design equations for the new band stop resonance frequency are presented together with the analysis of the correspondence between the band pass and band stop attenuation vs. the quality factor of the shunt and series inductors used. The filter is supported on a 6.4 μm thin dielectric membrane, and is manufactured using silicon micromachining, in CPW technology. Measurements illustrated a minimum 2.75 dB insertion loss at 5.5 GHz in the band pass, and more than 40 dB attenuation, at 8 GHz.
