Feeding Structure

A novel feeding structure in magneto-electric dipole antenna is proposed and analyzed, which is simpler and better in performance than previous designs, involving differential feeding.  Due to this improved feeding structure, the antenna has achieved an impedance bandwidth of 133.3% ( 0.5 GHz – 2.5 GHz, resulting into an ultra-wide band antenna. The maximum broadside gain 7.5dBi with unidirectional radiation pattern has also been reported for the entire the range of operation. Symmetry in E-plane and H-plane radiation patterns has been observed due to the symmetry in structure and excitation of antenna. The antenna has also been able to achieve cross polarization levels.

The optical antenna can be generated high frequency by laser light source from a micro-ring resonator system. The Gaussian pulse into the micro-ring resonator created the chaotic signal with converting the wavelength domain to frequency domain for radio broadcasting. The system designed by varies the micro-ring parameter in the wireless optical antenna. The high frequencies are 3.1 GHz-10.6 GHz for radiation dipole antenna. This system can be conversion from the wavelength domain to frequency domain (GHz) in ultra wide band, which can be application for optical antenna in near future.

Computer analysis reveals that the anomalous behavior of symmetric Log Periodic Dipole Array (LPDA)Antennahas infloenced by different parameters . The most important is mainly due to the radiation of the dipole elements in the anomalous radiating region which is excited by the transmission line resonance of the feed structure. In the design by changing the element spacing , changes of length of each element in the LPDA antenna and define cross eaching in an boom of an antenna in middle of the specified element the result is the return loss less from 200 MHZ to 1500 MHZ other than the notch between 850 MHZ 950 MHZ according to the simulation results.The log-periodical Dipole Antenna (LPDA) is a kind of ultra wide-band antennas. To achieve the purpose of miniaturization of the LPDA in radiate direction, this paper presents anunusual structure log-periodically loaded with slot cross-shape design.
