Abstract

In this paper, a cylindrical Dielectric Resonator Antenna (CDRA) with a dual feeding line is designed and investigated at 28 GHz. The dual feeds line is designed to excite the DR with multi relative permittivity which contributes to a high impedance bandwidth operation. The proposed single CDRA has been fabricated and mounted on a Rogers TMM 10i (tm)1 (?r = 9.8 and tan? = 0.002) substrate. The optimized single element has been applied to improve the gain and achieve the required gain performance. The radiation pattern, impedance bandwidth and gain are simulated. The proposed antenna obtains a reflection coefficient response from 26.2 GHz to 30 GHz which cover the desired frequency band. This makes the proposed antenna achieve 4.7 GHz impedance bandwidth and gain of 7 dB. Thus, it has potential for millimeter wave and 5G applications.
