Superconducting small antenna combined with a bandpass filter
نویسندگان
چکیده
A superconducting slot antenna combined with a bandpass filter composed of coplanar waveguide meanderline resonators has been designed and tested. Based on a new design theory for broadband impedance matching circuits, we designed a slot antenna with a small radiation resistance of 1 X impedance matched to a three-pole Chebyshev bandpass filter with 10 GHz center frequency and 0.35% fractional bandwidth. Experiments with a YBCO slot antenna on a MgO substrate have demonstrated the designed performance. 2002 Elsevier Science B.V. All rights reserved.

Superconducting Microstrip-Fed Antenna Coupled to a Microwave Kinetic Inductance Detector
A proper antenna to couple to a microstrip Microwave Kinetic Inductance Detector (MKID) is designed and simulated. A twin-slot microstrip-fed inline antenna is designed for frequency band of 600-720~GHz integrated with an elliptical lens and coupled to the MKID. A systematic design procedure for design of such antenna with microstrip inline feeding is presented. Whole structure of lens and twin...
متن کاملHigh-Temperature Superconducting Bandpass Spiral Filter
We report a new type of microstrip bandpass spiral filter structure, which exhibits much smaller size than other existing miniaturized bandpass filter structures, and is particularly useful in developing hightemperature superconducting (HTS) compact filters for cellular communication systems. A prototype three-stage HTS bandpass spiral filter with center frequency of 633 MHz was designed and fa...
متن کاملFractal Bandpass Filter Using Y-shaped Dual-Mode Resonator for C-Band Receiver (Research Note)
In this study, a fractal, Y-shaped dual-mode resonator bandpass filter (BPF) with input-output cross-coupling is introduced. A parallel-coupling feed structure with a cross coupling has been used to generate two transmission zeroes (TZs) near the lower and upper cutoff frequency that can effectively improve the passband edge selectivity. Also, a fractal shaped based on conventional diamond and ...
متن کاملA Novel Compact HTS Interdigital Bandpass Filter Using CPW Quarter-Wavelength Resonators
A novel high temperature superconducting interdigital bandpass filter is proposed by using coplanar waveguide quarterwavelength resonators. The CPW resonators are arranged in parallel, and consequently the filter becomes very compact. The filter is a 5-pole Chebyshev BPF with a midband frequency of 5.0 GHz and an equal-ripple fractional bandwidth of 3.2%. It is fabricated using a YBCO film depo...
متن کاملA Compact Ultra-Wideband Bandpass Filter with Sharp-Rejection using Complementary Split Ring Resonators
A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...
