The College of Education for Pure Sciences, Department of Physics, organized a scientific lecture on the theoretical investigation of a multi-layer double-fed ribbon-array antenna.
The lecture presented by the researcher (Doaa Hussein Hashem) included it is necessary in many applications to design antennas with very high gain to meet long-range communications. The gain and directivity in a single antenna is lower. To increase the yield and directivity the solution is to create an array antenna. This can be done by increasing the antenna size and often expanding the dimensions of the individual antenna leads to more directional characteristics. The other method is to increase the antenna dimensions without increasing the size of the individual antenna, which is the antenna array. The elements of the array can be fed by one or several lines in the arrangement of the feeding network.
This study proposes an analysis of a dual fed ribbon array antenna. The dual-feed ribbon antenna proposes to obtain circular polarization of radiation and a wide beam for applications.
The proposed antenna is expected to enhance the directivity in addition to improving the antenna parameters such as high directivity, radial structure, standing wave ratio (VSWR), return loss (loss factor) S-parameter and gain of the proposed antenna.
Objective of the lecture: The lecture aims to design and simulate a double-fed ribbon array antenna to increase the radiation properties such as gain, bandwidth, and obtain an appropriate radiation structure and other advantages. These results were presented during this lecture
