Computer-aided antenna feed design using Characteristic Modes

Bryan D. Raines;Ezdeen A. Elghannai;Roberto G. Rojas

2015 European Microwave Conference (EuMC)
Year: 2015 | Conference Paper |
Cited by: Papers (2)
A new design technique that provides practical feed designs for arbitrary PEC structures is introduced. The technique requires minimal guidance from a human operator Using the information provided by a modal analysis, known as Characteristic Modes, allows us to construct a feed arrangements solution(s). From this solution(s), we can obtain the number, locations, and excitation voltages of one or m...Show More

Multiport Reactive Loading Matching Technique for Wide Band Antenna Applications Using the Theory of Characteristic Modes

Ezdeen A. Elghannai;Bryan D. Raines;Roberto G. Rojas

IEEE Transactions on Antennas and Propagation
Year: 2015 | Volume: 63, Issue: 1 | Journal Article |
Cited by: Papers (32)
A systematic framework is presented for designing an antenna with arbitrary shape and expanding its input impedance and pattern bandwidths using reactive loading. This method, unlike other design procedures, allows us to control the current distribution over the antenna structure with potentially fine granularity. This technique is applied to wire and microstrip antennas and it is shown to achieve...Show More

Wideband Characteristic Mode Tracking

Bryan D. Raines;Roberto G. Rojas

IEEE Transactions on Antennas and Propagation
Year: 2012 | Volume: 60, Issue: 7 | Journal Article |
Cited by: Papers (59)
A method is proposed by which a large number of characteristic modes of an arbitrary structure are tracked over a very wide frequency range; it is necessary for any serious wideband modal analysis of complex structures. The method can track a large number of modes using the modal eigenvectors from a generalized eigenvalue problem parameterized by frequency and has been successfully applied to over...Show More

Wideband tracking of characteristic modes

Bryan D. Raines;Roberto G. Rojas

Proceedings of the 5th European Conference on Antennas and Propagation (EUCAP)
Year: 2011 | Conference Paper |
An overview of the problem of modal tracking in the discipline of characteristic modes is discussed and results of a proposed solution presented. It is placed in the historical context of mode tracking and alternatives are discussed, with reasons given for why they are not applicable to characteristic modes, requiring the development of a wideband modal tracking algorithm applicable to characteris...Show More

Design of multiband reconfigurable antennas

Bryan D. Raines;Roberto G. Rojas

Proceedings of the Fourth European Conference on Antennas and Propagation
Year: 2010 | Conference Paper |
Cited by: Patents (1)
Using the theory of network characteristic modes, a planar inverted-F antenna and a microstrip patch antenna are systematically modified to obtain multiband performance at arbitrary frequencies. Each is loaded at multiple points with reactive loads consisting of multiple lumped resonators computed directly using equations derived from network characteristic mode theory.Show More

Design of Frequency Reconfigurable Antennas Using the Theory of Network Characteristic Modes

Khaled A. Obeidat;Bryan D. Raines;Roberto G. Rojas;Brandan T. Strojny

IEEE Transactions on Antennas and Propagation
Year: 2010 | Volume: 58, Issue: 10 | Journal Article |
This paper demonstrates a design procedure for frequency tunable reconfigurable antennas based on the application of reactive loads. Unlike other design procedures, antennas of arbitrary geometry can be tuned utilizing the proposed design framework. The design technique utilizes the theory of network characteristic modes to systematically compute reactive load values required to resonate any anten...Show More

Application of Characteristic Modes and Non-Foster Multiport Loading to the Design of Broadband Antennas

Khaled A. Obeidat;Bryan D. Raines;Roberto G. Rojas

IEEE Transactions on Antennas and Propagation
Year: 2010 | Volume: 58, Issue: 1 | Journal Article |
Cited by: Papers (40)
A conceptual framework is proposed to systematically design antennas with broadband impedance and pattern characteristics using multiple reactive loads. Antennas of arbitrary geometry can have their bandwidths expanded using this technique. The technique is applied to a narrow band thin wire dipole antenna to demonstrate its main features. It is shown that the loaded antenna resonates a desired cu...Show More

2009 3rd European Conference on Antennas and Propagation
Year: 2009 | Conference Paper |
Cited by: Papers (2)
The method of characteristic modes is used to design a vertically polarized communications antenna conformal to the V-shaped tail of a small UAV. The antenna must operate in the band from 50 to 90 MHz and must be omni-directional. This antenna has a vertical dimension of lambda/17 at 50 MHz.Show More

2008 IEEE Antennas and Propagation Society International Symposium
Year: 2008 | Conference Paper |
Cited by: Papers (8)
Electrically small dipole antennas with ka less than 0.5 exhibit low radiation resistance, high capacitive reactance and high Q factor which is inversely proportional to antenna bandwidth. Here, the k is the free space wave number and a is the radius of an imaginary sphere which circumscribes the whole antenna. Spherical dipole antennas potently have higher effective volume if compared to other sm...Show More

The antenna under consideration is a five-turn Archimedean rectangular two-arm wire spiral antenna, which is 46 x 15.7cm in size is presented in this paper. It is placed in the x-y plane. There are two ports (one per arm) located at the center. Normally, a two-arm spiral antenna cannot practically radiate spiral mode 2, as it requires the two-ports at the center to be excited in phase (i.e. an unb...Show More
