Abstract
A quad-band circularly polarised (CP) patch antenna for 7.1/7.6/7.9/8.6 GHz for UWB/5G applications are proposed in this paper. By designing the patch antenna with an inverted U-shaped radiator, I-shaped and L-shaped strips which are all rotated by 45áµ’ at the horizontal axis. The measurement of -37.51 dB of return loss for 8.6 GHz frequency was obtained. A microstrip line feed technique was used for feeding which is one of the contacting schemes used in the feeding methods. A conducting strip is connected directly to the edge of the microstrip patch. It provides a simple planar structure since the conducting strip is smaller in size when compared to the patch. The substrate FR_4 epoxy has high electrical insulation, good mechanical strength, better wear, and corrosion resistance. The measured 3 dB AR information is 5.63% (6.9-7.3 GHz), 5.26% (7.4-7.8 GHz), 5.0% (7.8-8.2 GHz) and 3.50% (8.4-8.7 GHz) severally. This antenna can be used in UWB/5G applications which offer high-speed data transmission.

Important Announcements


All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
