Compact Microstrip Uwb Bandpass Filter with Triple-notched Bands
A new microstrip ultra-wideband (UWB) bandpass filter (BPF) with triple-notched bands is presented in this paper. The circuit topology and its corresponding electrical parameters of the initial microstrip UWB BPF are desired by a variation of genetic algorithm (VGA). Then, triple-notched bands inside the UWB passband are implemented by coupling a square ring short stub loaded resonator (SRSSLR)...
متن کاملCreating Band-Notched Characteristics for Compact UWB Monopole Antennas
In 2002, the FCC in the US authorized the unlicensed use of the ultrawideband (UWB) frequency spectrum for commercial applications in the range from 3.1 to 10.6 GHz with an emission limit of -41.3 dBm/MHz which is near to the thermal noise floor [1]. UWB communication systems operating in such a wide frequency band and low power emission level could easily be interfered by the existing nearby c...
متن کاملMultibeam Antennas With Polarization and Angle Diversity
A 10-GHz discrete cylindrical lens array with multiple beams is designed and characterized as a receiving angle-diversity array for wireless communications in a multipath environment. The array also has dual-orthogonal polarization and therefore built-in polarization diversity. The array is designed for wide-angle scanning between 45 and 45 and measured scanning patterns are presented. The pola...
متن کاملDesign and Time-domain Analysis of Compact Multi-band-notched Uwb Antennas with Ebg Structures
Four ultra-wideband (UWB) antennas are proposed: one referenced antenna without notch and three novel antennas with one, two and three notched bands, respectively. The UWB referenced antenna consists of a beveled rectangular metal patch, a 50 Ω microstrip line and a defective ground plane. Then, by utilizing one, two and three electromagnetic band-gap (EBG) structures on the UWB antenna, the an...
متن کاملNew Triangle-Ring UWB Bandpass Filter with Sharp Roll-Off and Dual Notched Bands
This paper presents a new ultra-wideband (UWB) bandpass filter (BPF) with sharp roll-off and dual-notched bands. The filter consists of a triangle ring multi-mode resonator (MMR) with the stub-loaded resonator (SLR) for controlling the two transmission zeros at 2.8 / 11 GHz, the embedded open-circuited stub and the asymmetric tight coupled input/output (I/O) lines for introducing the dual notch...
