Development and Analysis of Compact Lowpass Filter for UWB Systems
This paper presents a developed compact lowpass filter which is devised by concatenating ‘T’ and inverted ‘T’ open stubs on a microstrip line. They are combined to enhance the bandwidth and also to improve the outband performance. Insertion loss of the developed filter is less than -0.15 dB and the return loss is -30 dB at 2.85 GHz. Stopband performance of the filter is less than -20 dB from 5....
متن کاملCompact Microstrip Lowpass Filter with Wide Stopband and High Attenuation
A compact microstrip lowpass filter using radial stub resonators is developed. This filter is composed of two radial stub resonators that are asymmetrically connected to each other by a stepped impedance structure. This structure results in a very high rejection and wide stopband. The proposed filter with a 3 dB cutoff frequency of 2.07 GHz has been designed, fabricated and measured. Measuremen...
متن کاملCompact Lowpass Filter Design by using Triangle Shape DGS
Most communication system contains an RF front end which performs signal processing with RF filters. Micro strip filters are a low cost means of doing this. Micro strip filters play various roles in wireless or mobile communication systems. There is an increasing demand for newer microwave and millimetre-wave systems to meet the emerging telecommunication challenges with respect to size, perfor...
متن کاملresource management for 5g-satellite communication systems based on queuing theory
nowadays, with the advent of new satellite services, the need for resource management in the emerging fifth generation satellite systems (5g-satellite) is inevitable. thus, to solve this problem, the bandwidth manager for resource reservation in satellite link is mandatory. on the other hand, due to limited resources, their resource management is essential. in order to resource management in 5...
متن کاملdesigning unmanned aerial vehicle based on neuro-fuzzy systems
در این پایان نامه، کنترل نرو-فازی در پرنده هدایت پذیر از دور (پهپاد) استفاده شده است ابتدا در روش پیشنهادی اول، کنترل کننده نرو-فازی توسط مجموعه اطلاعات یک کنترل کننده pid به صورت off-line آموزش دیده است و در روش دوم یک کنترل کننده نرو-فازی on-line مبتنی بر شناسایی سیستم توسط شبکه عصبی rbf پیشنهاد شده است. سپس کاربرد این کنترل کننده در پهپاد بررسی شده است و مقایسه ای ما بین کنترل کننده های معمو...
