A new LP Prototype-to-Distributed Bandstop mapping is defined to synthesize BSF's with controllable upper pass bandwidths. The synthesized filters involve resonators made up of commensurate OC and SC stubs coupled by inverters. It is shown that when inverters are approximated by several unit elements (UE) then their contribution to the response increases appreciably upon optimization. Thus, a novel approach is developed which can be used to synthesize BSF's with contributing UE's having ultra wide upper pass bands. Examples are presented with stopband centered at 1 GHz and having upper passband extending to 18 GHz.

Synthesis Approach for Compact Ku-Band Waveguide Lowpass Filters with Wide Rejection Bandwidth Cetin, Metehan; Boyacioglu, Gokhan; Alicioglu, Bulent; Yıldırım, Nevzat (2018-11-02) Classical corrugated waveguide (WG) LP filters with wide rejection bandwidths rely on designing a band stop block with reduced height waveguides augmented by impedance matching blocks at terminations. In this paper direct synthesis approach is used to synthesize the whole filter as a single unit. The initial filter is designed as a TEM mode commensurate length LPF with very high quarter wavelength frequency for size reduction. Filter is made up of series SC stubs interlaced by contributing Unit Elements (UE...
Design of Microstrip Quadruplet Filters on Filpro Oruc, Sacid; Yıldırım, Nevzat (2018-11-02) In this paper, a simple dimensional design procedure is developed for microstrip/stripline quadruplet filters by starting with direct BP synthesis of a lumped quadruplet with inverter couplings, K14, K12, K23 and K34. K14 is the cross-coupling inverter which creates a symmetric pair of finite transmission zeros (FTZ's) if the sign of K14 is opposite of the other inverters while a complex TZ is created if K14 has the same sign as the other inverters leading to linear phase (flat delay) responses. The LC reso...
Attitude estimation for nanosatellites ssing Singular value decomposition and unscented kalman filter Söken, Halil Ersin; Çilden Güler, Demet (null; 2015-07-10) The singular value decomposition (SVD), one of the single frame attitude estimation methods, is used together with the unscented Kalman filter (UKF) for nanosatellite attitude estimation. The proposed interlaced algorithm estimates the attitude and gyro biases using three attitude sensors onboard, which are magnetometers, sun sensors and gyroscopes. The algorithm uses the SVD method at first to estimate the optimal attitude by minimizing the Wahba's loss function. In the second phase, the UKF takes this inf...
On Miniaturization and Performance Improvement of Planar Wideband Bandpass Filters Without Coupled Lines Alicioglu, Bulent; Yıldırım, Nevzat (2009-10-01) Two classical approaches are compared in various respects for the design of wideband planar BPF's without parallel coupled lines, namely, BPF's designed by pole placement with contributing Unit Elements (UE) and inverter coupled resonator filters designed from LP prototypes. It is shown that the circuit obtained by direct BP synthesis is a special case of inverter coupled filter with inverters converted into single Unit Elements. It is also shown that if the inverters are converted into odd number of UE's t...
Non-linear filtering based on observations from Gaussian processes Gustafsson, Fredrik; Saha, Saikat; Orguner, Umut (2011-03-12) We consider a class of non-linear filtering problems, where the observation model is given by a Gaussian process rather than the common non-linear function of the state and measurement noise. The new observation model can be considered as a generalization of the standard one with correlated measurement noise in both time and space. We propose a particle filter based approach with a measurement update step that requires a memory of past observations which can be truncated using a moving window to obtain a fi...
