Abstract:

This paper contains a novel design of a horn antenna control system for microwave applications. Using “Fermat’s principle” the horn antenna is designed and fabricated. For microwave applications, high gain and low voltage standing wave ratio(VSWR) is needed, so for that purpose horn antenna is fabricated. In a previous paper, they designed the Yagi Uda antenna which is used for multiple driven elements by the method called maximum power transmission efficiency. For multiple driven elements, the horn antenna cannot be fabricated. If suppose yagi uda is fabricated using the principle called Ferm

Abstract RF (Radio Frequency) connector has been extensively applied in the field of communication for it is a key device of transmitting microwave signals. If he RF connector end is designed improperly in dimension, a clearance will be observed after inserting, resulting in an abnormal phenomenon in the voltage standing wave ratio (VSWR) of the RF connector. This paper studied the influence of the inserting clearance of RF connector on the voltage standing wave ratio through theoretical analysis and performance simulation. Moreover, the solution to the abnormal voltage standing wave ratio was

The high-frequency behavior of superconducting NdBa 2 Cu 3 O 6+x (NBCO) has been investigated by the standing-wave technique in the microwave region. The joule loss of the bulk NBCO sample, as determined from the voltage standing wave ratio (VSWR), falls markedly at Tc. In the low temperature region, i.e. for T<Tc it tends towards the formula, A=18.5 exp (-0.052 eV/kT).

Abstract: Microstrip Patch Antennas (MPA) have shown to be the most unusual finding in the era of downsizing, despite the fact that the revolution in antenna engineering has led to the rapidly expanding communication networks. The design, modeling, and analysis of rectangular microstrip patch antennas are all included in this study. The suggested patch antennas' resonating frequency is 9 GHz, which falls inside the X band area. Ansys HFSS software was used to design them using Rogers RT/duroid 5880 material, which has a dielectric constant of 2.2. Five performance metrics were used to assess t
