Meandered monopole coupled loop antenna
2012 6th European Conference on Antennas and Propagation (EUCAP), 2012A printed open-circuit monopole coupled loop antenna (MCLA) operating around 425 MHz is proposed in this communication. This antenna is an evolution of the MCLA, where meander lines have been added. It achieves to a very compact antenna operating in UHF. The theoretical and measurement results are presented.

Unidirectional printed loop antenna
6th International SYmposium on Antennas, Propagation and EM Theory, 2003. Proceedings. 2003, 2003A new type of printed rectangular loop antenna with capacitive loads is proposed for unidirectional radiation pattern production. The arrangement presented here is shown to have a current distribution with balanced magnitude and 90/spl deg/ phase difference on parallel radiating edges of the loop. As a result, the printed loop is equivalent to an array

A rather simple and general analysis allows calculation of the transient response of many different radiators of practical interest directly in the time domain without the knowledge of the corresponding time harmonic field. Here, we present exact expressions for the transient near-and far-fields around thin circular current loops of arbitrary ...

2008 International Conference on Recent Advances in Microwave Theory and Applications, 2008
In this paper, an inward scaled loop antenna (ISLA) is presented. It is created by successive scaling and rotating and fitting the scaled copies of a wideband loop antenna (WBLA) in the empty space available in it. The overall size of the antenna remains the same as that of the WBLA.

Periodic spherical loop antenna
2015 IEEE 16th Annual Wireless and Microwave Technology Conference (WAMICON), 2015In this paper a volumetric approach to miniaturizing a 300 MHz loop antenna is presented. Leveraging the benefits of additive manufacturing allows for the antenna to be meandered in a spherical pattern resulting in higher levels of miniaturization while maintaining efficiency.

The Quadruple Loop (QL) antenna was designed and investigated to deliver a robust body-worn antenna for bio-medical applications. The QL antenna is a very thin single-layer groundless structure which allows for the installation of neighboring electronics and sensors on biomedical device.

A new type of wire loop antenna has been developed for the production of circular polarization. The antenna was obtained by twisting a one-wavelength square loop with two small gaps at the middle of its two non-radiating sides. The twisted loop antenna can achieve circular polarization with axial ratio less than 1 dB at broadside.

This chapter introduces another fundamental antenna configuration: the loop antenna. This simple, inexpensive, and very versatile antenna takes many different forms, such as a rectangle, square, triangle, ellipse, and circle. Because of the simplicity in analysis and construction, the circular loop is the most popular and has received the widest ...

Revisiting Rectangular Loop Antenna
Advanced Science and Technology Letters, 2013This paper is a study of rectangular wire loop antenna at different side ratios using EZNEC+ v5.0 simulation software. Four wire diameters are considered. The rectangular antenna is configured at two different perimeter lengths. One length was 1-λ long, and the other is resonant length at square configuration.
