Bandwidth Enhancement and Generation of CP of Yagi-Uda-Shape Feed on a Rectangular DRA for 5G Applications

Both theoretically and experimentally, a wideband circularly polarized rectangular dielectric resonator antenna fed by a single feeding device has been investigated scientifically and experimentally. The aim of the investigation is to see how adding a parasitic strip next to the flat surface metallic feed will change various far- and near-field antenna characteristics. The antenna-B delivered a good result as compared to antenna-A, but the network needed to be expanded, for which a parasitic patch was added next to the Yagi-Uda antenna on the rectangular DRA at an optimized location to further enhance the antenna's performance. These results show that parasite patches, in addition to producing CP, caused the return loss to increase by a factor of nearly three times when compared to those obtained with the Yagi-Uda-shape feed alone. The planned antenna geometry prototype was constructed and tested.

A compact dual band MIMO antenna for 5G/WLAN applications

The measured u221210 dB reflection coefficients frequency bands are 3. 3 u20133. 8 and 4. 3 GHz, respectively. The measured isolation S 21 between the two radiating elements is greater than 15 and 17 dB at the lower and higher frequency bands, respectively. According to the measured results, the tested antenna will be a good candidate for 5 G/WLAN wireless communications.

Design and Analysis of Novel Reconfigurable Monopole Antenna Using Dip Switch and Covering 5G-Sub-6-GHz and C-Band Applications

This research reveals a novel frequency-reconfigurable antenna that may be the first to use a dip switch and a bias circuit integrated on the same substrate as the antenna. Since it is small and versatile enough to work in many frequency bands with different modes, such an antenna can be used for many wireless applications. MODE 1, MODE 2, MODE 2, and MODE three, respectively, and the triple band in MODE 4. The new antenna operates in four modes, covering nine different bands by using three dual bands in MODE 1, MODE 2, MODE 2, and MODE 3, respectively. The recommended antenna can be used in current portable electronics and the IoT. The suggested antenna can be used in current portable electronics and the IoT.
