Truly Conical Eleven Antenna: a New Geometry for Applications at High Frequencies
Paper in proceeding, 2016

A new truly conical geometry of Eleven antenna for high frequency applications is proposed in the paper. By using this geometry, the antenna petal arrays are made on only one piece of flat thin PCB, which is soft enough to be conically bent and strong enough after the conical bending to be fastened stably by only the center pack cone and the outer walls. Therefore, many manufacture difficulties by using previous Eleven antenna geometries have been avoided. Simulated performance of a 4.6–20GHz Eleven feed, -10 dB reflection coefficient and above 60% aperture efficiency when feeding a reflector antenna, is presented as an example in the paper.
