“…Electric field (E‐field) distribution of PD at 5.8 and 6.1 GHz frequency is analyzed and shown in Figure . It can be monitored that the propagating mode is similar to hybrid mode, that is, EH 11δ like‐mode for the entire operating band in reference to the corresponding cylindrical resonator mode …”

“…It can be monitored that the propagating mode is similar to hybrid mode, that is, EH 11δ like-mode for the entire operating band in reference to the corresponding cylindrical resonator mode. 20 The reflection coefficient vs frequency for all optimized antenna of each step are shown in Figure 14. Similar, Figure 15 shows the impedance variation vs frequency of PD in which it can be observed that the magnitude of the average impedance is around 50 Ω within most of the operating band.…”

The design and development technique for the enhancement of bandwidth and gain using biodegradable star‐shaped dielectric resonator antenna (SDRA) electrified by two cross‐coupled apertures for broadband applications is presented in this article. The SDRA is fabricated using biodegradable PLA, which is a special type of polymer and made from renewable resources instead of nonrenewable petroleum‐based resources using additive manufacturing technique. Broad bandwidth of 37% is achieved by modifying rectangular dielectric resonator antenna with feeding it by two apertures (slots) of unequal length to excite different modes. The combination of the circular‐shaped split‐ring resonator has been used as a metamaterial for gain enhancement, which enhanced the maximum gain of the antenna by ∼5.4 dB (82.7%). The computed average efficiency within the operating band is ∼80.51%. The proposed antenna is circularly polarized at 5.8 GHz. The proposed antenna fulfills the bandwidth requirements for the IEEE 802.11a WLAN standards (5.15‐5.35 and 5.725‐5.825 GHz), and it is also suitable for various other applications such as satellite navigation systems, aeronautical and meteorological radio navigation services in C‐band.

This article presents the design and development of a low profile substrate integrated waveguide semi-circular cavity-backed antenna loaded with dielectric cylinders of glass-reinforced epoxy and Teflon. The substrate integrated waveguide semi-circular cavity-backed antenna without dielectric loading radiates at 5.8 GHz with 3.13 dB gain. The antenna is modified by putting dielectric cylinders of different materials and different sizes at the edge of a semi-circular cavity to enhance the gain of the antenna. The new antenna thus created has improved gain of 8.13 dB. All simulations are done using high frequency structure simulation software. The proposed design is fabricated on a glass-reinforced epoxy substrate with a semi-circular cavity having a size of 60 mm × 50 mm. The measured results are in good agreement with simulated ones.
