Otimização dos parâmetros de monopolos planares de microfita para aplicações em sistemas de banda ultra larga
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2008-10-21)
This work presents a theoretical and experimental investigation about the properties of microstrip antennas for ultra-wideband systems. Configurations of elliptic monopoles with different eccentricities and circular monopoles ...
A TRIPLE-MODE BANDPASS FILTER USING A MODIFIED CIRCULAR PATCH RESONATOR
(JOHN WILEY & SONS INC, 2009)
This article presents a triple-mode bandpass filter using a modified circular patch resonator. Etched slots in the resonator split the TM(1, 1, 0)(z) degenerate fundamental modes and also perturb the TM(2, 1, 0)(z) mode, ...
Análise de antenas de microfita com patches circulares sobre substratos anisotrópicos usando o método dos potenciais de Hertz
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2005-03-31)
This work consists on the theoretical and numerical analysis of some properties of circular microstrip patch antennas on isotropic and uniaxial anisotropic substrates. For this purpose, a full wave analysis is performed, ...
Optimización de antenas microstrip coplanar y circular para aplicaciones BAN a 2.45GHz
(Universidad Inca Garcilaso de la Vega, 2012-10)
Una optimización preliminar de antenas microstrip (patch) localizadas sobre superficies biológicas. El análisis es desarrollado en la banda de 2.4 GHz ISM para redes de área corporal y personal. Las simulaciones se llevaron ...
Strong interaction between plants induces circular barren patches: fairy circles

Bi anisotropia em antenas de microfita retangular e estruturas circulares modificadas
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO, 2015-11-20)
The microstrip antennas in your simplest form consist of a ground plane and a dielectric substrate which supports a conductive tape. As these antennas have some limitations, this work presents a study of anisotropic ...
Pentagonal Microstrip Antenna Equivalent to a Circular Microstrip Antenna for GPS Operation Frequency
(Universidad Autónoma del Estado de Morelos, 2009)
Analysis of a Reconfigurable Bandpass Circular Patch Filter
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper presents an analysis of a reconfigurable patch filter based on a triple-mode circular patch resonator with four radial slots. The analysis has been carried out thanks to the development of a new theoretical ...
