Keywords:
Compensation phase, double conformal rings, transmitarray antennaAbstract
In this paper, we mainly study the electromagnetic transmission characteristics of transmission array antennas and transmission units. Based on array antenna theory and geometric theory, we construct a transmission array antenna for a double conformal rings (DCR). It works in a 10GHz two-layer transmission array. A double resonant conformal rings are used as the unit element. By changing the physical dimensions of the double conformal unit, phase coverage of up to 600° can be achieved. And the 1d B gain bandwidth is has by 7% compared to the previous transmission array. The simulated and measured peak gain is 27.59 dB and 25.91dB, respectively.
