“…Microstrip patches are mostly extensively used in wireless devices due to its less weight, ease of fabrication and better design optimization solutions [1]- [2]. It ranges from linear polarized [3] to circular polarized [4] patches, narrowband to ultra-wideband patches. This patch plays a crucial role in radar systems, satellite communications, military, and airborne communications and remote sensing applications.…”

The paper presents a novel dual-band patch working at GSM band and S-band. The patch encompasses a rectangular radiator coupled with a parasitic patch in the coplanar region and a split ring resonator in the ground region. The patch is analyzed numerically and is synthesized using the HFSS simulator. Finally, the performance characteristics of the model are measured and are compared with numerical and simulated results. The patch gives two different bands at 950MHz and 2.3GHz and gives -10dB impedance bandwidth in the lower band from 950MHz -1GHz and higher band from 2.275GHz – 2.325GHz. The patch also accomplishes a gain of 4.74dBi in the effective band 1 and 4.02 dBi in the operating band 2.

“…As indicated in the review of omnidirectional antennas [2][3][4][5][6][7][8], a uniform radiation pattern with horizontal polarization in the azimuthal plane is obtained by summing the radiation patterns of elementary high-frequency dipoles with identical inphase and equally-amplitude excitation placed along the ring with the same angular offset relative to the central axis. The number of elementary dipoles spread around the circle will obviously be unequivocally related to the radius of the CA and the size of the dipole (the resonance frequency of the dipole).…”

“…More promising way is to implement such antennas in the form of a circular array (CA), composed of electrically small antennas with horizontal polarization connected in parallel, for example, dipoles, logoperiodic antennas or Vivaldi emitters placed along the ring with the same angular offset relative to the central axis. As indicated in the works [2][3][4][5][6][7][8], CA of electrically small parallel dipole or slot elements of different shapes are mostly used in such antennas. The antennas presented in these works are designed to operate at frequencies above 1 GHz, but when switch to lower frequencies is performed, their dimensions increase rapidly, which limits their use.…”

Ommidirectional in azimuth plane antennas with horizontal polarization are used in communication systems of McWILL standard, digital television systems of DVB-T2 standard, radio monitoring systems, semi-active ranging using the target illumination with the television broadcast signal, and many other cases. In many cases, radar and radio monitoring systems use phase methods to determine the azimuth and elevation angle of the target. To view all azimuthal angles, ring arrays consisting of omnidirectional emitters, usually also represented by ring arrays, are used. This paper studies the characteristics of an omnidirectional radiating element of electrically small horizontal dipole elements. An expression is derived that relates the radius of the dipole ring array to the number of dipoles and the variation of the resulting radiation pattern. The results are confirmed by experimental studies.
