A one-eighth spherical surface dielectric resonator antenna (OESS-DRA) is proposed first time. To analyze this thin shell structure, electromagnetic fields distribution is discussed by using the Hertz vector and boundary conditions. We simplify the solution of Maxwell equations by using Hertz vector because the polarization current is primary in the OESS-DRA. The Hertz vector can be expressed the current better. This proposed antenna is composed of one-eighth spherical dielectric shell fed by coaxial probe; and the ground with metal-corner-reflector makes the antenna with high gain and directional radiation properties. To verify this design, a fabricated sample is tested; results show the antenna covering bandwidth 4.56-6.88GHz, a high gain greater than 9.5dBi (peak gain 11.8dBi at 5.0GHz), and a high radiation efficiency over 85% in the entire working frequency band, as well. The OESS-DRA can be a good candidate in 5 th generation communication applications. INDEX TERMS Antenna, broadband, coaxial fed probe, directional, Hertz vector, one eighth spherical surface dielectric resonator.

“…The proposed SDRA working at 5.8GHz. SDRA is widely commercialized for up to date 5G networks.Currently LTE used band 42 at 2.6GH and 5G used band 43 at 3.5 GHz in wireless communication systems [11] [12]. Due to requirement of faster data transfer well past the 4G wireless standard .4G wireless standard is 100 times slower then the fastest 5G standard.…”

In this article Spherical DRA has been formulated , simulated and proto type developed. The detailed theoretical analysis along with simulations and measured results at 5.8 GHz have been presented in this article. The SDRA at 5.8 GHz covering 5G frewuenci band. The proposed design antenna provides the gain of 7.3 dB and return loss -25 dB. The measured results are in good match with simulated result. The proposed SDRA are good for 5G wireless networks, as well as other sub-6 band in wireless communication systems.
