Novel Compact and High Selectivity Dual-band BPF with Wide Stopband [PDF]

, 2012
A novel type of compact and high selectivity dual-band bandpass filter (BPF) incorporating a dual-mode defected ground structure resonator (DDGSR) and a dual-mode open-stub loaded stepped impedance resonator (DOLSIR) is proposed in this paper.

Retrodirective Antenna Array Using High Frequency Offset [PDF]

, 2012
The paper deals with the design of a simple retrodirective antenna array exhibiting by high frequency offset between received and transmitted wave. Analysis of the beam pointing error using antenna array model developed in MATLAB is described.

Optimisation of DSF and SOA based phase conjugators by incorporating noise-suppressing fibre gratings

, 1997
We compare the performance of dispersion-shifted-fibre (DSF) and semiconductor-optical-amplifier (SOA) based phase conjugators for a 10 Gb/s non-return-to-zero system with respect to conversion efficiency, noise figure and distortion.

Photonic RF and microwave reconfigurable filters and true time delays based on an integrated optical Kerr frequency comb source

, 2018
We demonstrate advanced transversal radio frequency (RF) and microwave functions based on a Kerr optical comb source generated by an integrated micro-ring resonator.

Bandpass filter design with spurious frequency reduction capability [PDF]

, 2014
Passband microstrip coupled line filter are widely used in daily microwave engineering practice. There are various topologies to implement microstrip bandpass filters such as end-coupled, parallel coupled, hairpin, interdigital and combine filters.

Compact Planar Microwave Blocking Filter [PDF]

This paper proposes a technique to design a compact planar broadband microwave blocking filter. The filter is constructed from multiple sections of bandstop filters with means to control radiation loss. As a result, the filter has small physical size and

Unsymmetrical bandpass and bandstop digital filters

Electronics Letters, 1969
The letter describes a transformation yielding unsymmetrical bandpass and bandstop filter pulse-transfer functions (p.t.f.s) by transforming a reference lowpass p.t.f. This function turns out not to be directly realisable since it is not an allpass transformation.
