This paper proposes a new design of a reconfigurable bandpass filter based on an interdigital capacitor and varactor diode for wireless and mobile applications. The designed reconfigurable bandpass filter has been implemented on an RT 6010 substrate with a relative dielectric constant of 10.2, thickness of 1.27 mm, and loss tangent of 0.0023. In or...
The goal of this paper is to design and develop of an ultra-wideband (UWB) hybrid coupler with a variable phase shift (90°–180° and vice versa) which operates around the resonant frequency of 3.8 GHz required for 5G applications. The design approach is based on the microstrip waveguide technique with localized lumped elements to control the phase s...
This paper presents the design of a compact bandpass filter based on two identical rectangular resonators and is implemented on microstrip technology for Wi-Fi and bluetoothapplications. To reduce the size of the filter, the defected microstrip structure (DMS) technique is proposed. This technique consists of etching slots in the rectangular resona...
The main objective of this work is the study, design and simulation of a narrow-band compact band pass filter using the technique of a rectangular-shaped linear resonator closed on a capacitive load and based on magnetic coupling. This filter is intended for wireless communication systems (Wi-Fi, Bluetooth, RFID, and ISM). It is attractive consider...
A new compact millimeter-wave bandpass filter combining SRRs and CSRRs is designed to be used in the future communication systems. By etching two CSRRs in the ground plane of the SRR bandpass filter, good performances are obtained. The simulated return loss and insertion loss of the proposed filter operating at 26 GHz are better than −24 dB and −0....
This paper presents the design of a compact band pass filter based on two identical rectangular resonators operating at 2.4 GHz. The shape of the rectangular resonators is modified to reduce the size of filter by etching the slot DMS. The designed filter has a compact size (6.82x8.3) mm² with low insertion loss as-0.1dB and good return loss as-15dB...
