| description | This paper proposes a dual-band circularly polarized (CP) rectangular dielectric resonator antenna (DRA) for 5G millimeter wave wireless communications. The proposed DRA consists of a novel modified cross-flower exciting (MCF) slot and a rectangular ceramic dielectric resonator (DR). With the help of the compact MCF feeding slot, the fundamental modes <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msubsup><mrow><mrow><mi>TE</mi></mrow></mrow><mrow><mi>δ</mi><mn>11</mn></mrow><mi>x</mi></msubsup></mrow></semantics></math></inline-formula>/<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msubsup><mrow><mi>TE</mi></mrow><mrow><mn>1</mn><mi>δ</mi><mn>1</mn></mrow><mi>y</mi></msubsup></mrow></semantics></math></inline-formula> and higher-order modes <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msubsup><mrow><mi>TE</mi></mrow><mrow><mi>δ</mi><mn>13</mn></mrow><mi>x</mi></msubsup></mrow></semantics></math></inline-formula>/<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msubsup><mrow><mi>TE</mi></mrow><mrow><mn>1</mn><mi>δ</mi><mn>3</mn></mrow><mi>y</mi></msubsup></mrow></semantics></math></inline-formula> of the DR can be excited to achieve CP dual-band characteristics. In addition, the MCF slot works as a radiator at 26 GHz and 39 GHz to enhance the DRA bandwidth. More importantly, these two operational bandwidths can be controlled independently at the lower and upper bands. The proposed DRA is designed, fabricated and measured. The measured results show that the proposed dual-band CP DRA achieves 3 dB axial-ratio (AR) bandwidths of 19.8% and 7.8% with peak gains of 5.62 dBic and 6.74 dBic for the lower and upper bands. |
