In this communication, ring dielectric resonator antenna is structured and investigated. Dual interrelated circular ring is used to stimulate the ring ceramic material. Three essential appearances of proposed radiator are: (a) interrelated circular ring is used to excite HEM_11δ and TE_01δ mode in ring-shaped ceramic; (b) T-shaped microstrip line along with linked circular ring is helpful to create CP waves in both operating frequency ranges; and (iii) proposed radiator supports LHCP and RHCP waves in lower and upper frequency range, respectively. Experimental data confirm that proposed antenna works over two frequency ranges i.e. 2.28–2.93 GHz and 4.26–4.65 GHz, respectively. CP waves are also supported in both lower and upper working frequency ranges i.e. 2.55–2.87 GHz and 4.41–4.65 GHz, respectively. This aerial is employable for WLAN (2.5 GHz) and INSAT (4.4 GHz) applications.

在该通信中，构造并研究了环形介质谐振器天线。双相环环是用来刺激环的陶瓷材料。所提出的辐射器的三个基本外观是： (a) 相互关联的圆环用于激发环形陶瓷中的HEM _11δ和 TE _01δ模式；(b) T 形微带线和相连的圆环有助于在两个工作频率范围内产生 CP 波；(iii) 提议的辐射器分别支持低频和高频范围的 LHCP 和 RHCP 波。实验数据证实，建议的天线工作在两个频率范围内，即分别为 2.28-2.93 GHz 和 4.26-4.65 GHz。在较低和较高工作频率范围内也支持 CP 波即分别为 2.55–2.87 GHz 和 4.41–4.65 GHz。该天线可用于 WLAN (2.5 GHz) 和 INSAT (4.4 GHz) 应用。
