The Filtering Performance of a Kind Antenna Model

2009 International Forum on Information Technology and Applications, 2009
This paper investigates the filtering performance of a new kind of compact antenna model, the cube antenna model. At first, the explicit expression for the signal to interference-plus-noise ratio (SINR) is obtained in terms of the parameters of the signal, interference, and noise.

An antenna-filter codesign for cardiac implants

2011 Design, Automation & Test in Europe, 2011
This paper presents the design of a 2.4 GHz antenna and a BAW filter for cardiac implants in the ISM band. These components are both sensitive to their environment. The antenna modelisation in human body is presented in order to characterize its impedance.

Horn Antennas With Integrated Notch Filters

IEEE Transactions on Antennas and Propagation, 2015
In this communication, we present the design of filtering horn antennas with band-stop characteristics obtained through the use of electrically small magnetic resonators. In particular, a split-ring resonator (SRR) etched on a Rogers Duroid RT5870 dielectric substrate is inserted within the metallic flare of the horn at a proper distance from the ...

A Filtering Microstrip Antenna Array

IEEE Transactions on Microwave Theory and Techniques, 2011
A new filtering microstrip antenna array is presented. The antenna elements, together with the very compact feeding network, function as a third-order bandpass filter. The feeding network, which consists of one power divider and two baluns, provides the first two stages, and the microstrip antenna elements provide the last stage in the filter design ...

An integrated filtering antenna of terahertz antenna-in-package

IET International Radar Conference 2013, 2013
An integrated THz filtering antenna of AIP (antenna in package) is proposed. As the indispensable parts of THz AIP, antenna and filter are designed together and fabricated by MEMS (Micro-electromechanical System) technology on silicon substrate. A MEMS H-plane horn antenna from 400GHz to 500GHz is designed as AIP antenna element, and a well designed E ...

Kalman filter for adaptive antennas

Wuhan University Journal of Natural Sciences, 1998
Adaptive control algorithm is a key technique for an adaptive array. It is necessary to find a fast and efficient algorithm for gaining rapid interference suppression. Convergence speed of conventional gradient-based algorithms is extremely slow and very sensitive to eigenvalue spread of autocorrelation matrix.

Integration of filters and microstrip antennas

IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2003
A new implementation of the integrated antenna-filter module has been proposed that is based on the single material technology and uses the same substrate for both the antenna and filter layers. An X band device has been designed on the low permittivity substrate and examined for X band operation. This example proves the feasibility of achieving a well-

Filtering Antennas and Filter-Valve Circuits

Proceedings of the IRE, 1929
Some methods of coupling together many circuits or antennas giving them simultaneous excitation from the same source of energy are described. The purpose of such arrangements is the construction of practical filter circuits (filtering antennas) giving square-topped resonance curves with good efficiency.

Performance analysis of filtering antennas

2017 International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2017
Multifunction module performing both filtering and radiating functions called filtering antenna or filtenna becomes inevitable in modern wireless communication system. This paper discusses the implementation of various filtering antennas and analyzes the performance of these antennas in terms of parameters such as gain, selectivity, bandwidth, harmonic

A Filtering Antenna Based on Stripline Low Pass Filter

2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2018
A filtering antenna based on strip line low pass filter with wide stop band and sharp roll-off is presented in this paper. The low pass filter has a good performance on a wide stopband lower than −25dB from 2.85GHz to 10.9GHz and a sharp roll-off from 2.6GHz (-3dB) to 2.9GHz (-39dB). The insertion loss is less than-ldB at pass band.
