The Cylindrical Omnidirectional Patch Antenna
IEEE transactions on antennas and propagation, 1997In recent years, the need for omnidirectional (in the azimuthal plane) antennas with narrow beams in the elevation plane, for wireless applications increased considerably. The antennas are used in amny frequency bands anywhere from 0.8 to 6 GHz. In a variety of configurations. The different collinear-array configurations are designed using back-to-back

Slotted patch antenna loaded with ferrite
2016 5th International Conference on Multimedia Computing and Systems (ICMCS), 2016This study presents the investigation on the effect of rectangular slot on resonance frequency, return loss and band widths, gain and directivity of rectangular microstrip patch antenna. The design is achieved by cutting the rectangular slots at the radiating element of the patch antenna; in the other step we loaded the films of ferrite between the ...

Microstrip patch antenna for RFID applications
2009 Canadian Conference on Electrical and Computer Engineering, 2009The microstrip patch antenna is a popular printed resonant antenna for narrow-band microwave wireless link applications such as radio frequency identification (RFID) systems that require semi-hemispherical coverage. In this paper, a 865 MHz microstrip patch antenna fed by a microstrip line designed on a substrate is considerably studied and thoroughly ...

Beam scannable microstrip patch antenna
2014 International Workshop on Antenna Technology: Small Antennas, Novel EM Structures and Materials, and Applications (iWAT), 2014A novel beam scanning technique of a ferrite loaded microstrip patch antenna is presented. Beam scanning is produced from controlled interaction of the radiated fields and the gyromagentic properties of the axially magnetized ferrite rods. By varying the magnetizing fields of the ferrite rods, optimally placed in the near field region of the antenna ...

IEE Colloquium on Antennas for Automotives, 2000
A variety of antennas have been presented which are suitable for manufacture on glass or on or behind plastic panels. These cover the frequency bands currently required for car antennas. New bands will need to be incorporated to cover UMTS for example and current designs are being expanded.

Novel Metamaterials for Patch Antennas Applications
2009In this paper we introduce the incorporation of magneto-electric materials into antenna design and the potential of controlling the behavior of the antenna by means of an external magnetic field. After an intensive study of magneto-electric material properties, a ferrimagnetic compound called Yttrium Iron Garnet (YIG) was found to be the best candidate

When constructing antennas it is popular to use printed metal patterns on multilayer substrates to obtain thin profile, conformability to smooth structures, and low manufacture cost. If the structure is planar or if the curvature of the structure is small, we can analyze the problem by considering a planar structure of infinite extent.
