自相似天线提供极高的宽带功能和易于扩展的设计。具有四臂布局的自相似设计也适用于通过激发相反的手臂来实现双偏振，尽管它们在毫米波探测器中的使用有限。这些天线已被用于测量宇宙微波背景(CMB)，该背景覆盖了很宽的频率范围，现在正积极地更多地关注极化各向异性。通过在高频结构模拟器上的仿真和正在进行的物理测试，分析了多个平面自相似天线的设计。它们都表现出130到230 GHz的宽带工作，并且可以通过前面提到的四臂对称耦合到两个线性极化。模拟包括每个天线设计耦合到一个扩展的半球形、涂有AR涂层的小透镜。因此，基本的蝴蝶结状臂设计产生了最小的偏振抖动，具有中等的光束效率，而混合梯形设计提供了高光束效率和较小的偏振抖动。目前正在测试每种器件的制造版本，并将其与多色微波动态电感探测器相耦合。这些平面自相似天线，当在CMB和其他探测器中实施时，可以改善观测，同时简化制造和探测器布局。
Self-similar antennas offer extremely broadband functionality and easily scalable designs. Self-similar designs with a four-arm layout are also suited for dual polarization through excitations of opposing arms, although there has only been limited use of them for millimeter-wave detectors. These antennas have been used for measurements of the cosmic microwave background (CMB), which encompass a wide frequency range and are now actively focusing more on polarization anisotropies. We analyze multiple planar self-similar antenna designs with simulations in high-frequency structure simulator and ongoing physical testing. They all exhibit broadband operation between 130 and 230 GHz and can couple to both linear polarizations through the previously mentioned four-arm symmetry. Simulations include each antenna design coupled to an extended hemispherical, AR-coated lenslet. From these, a basic bowtie-like arm design produced minimal polarization wobble with moderate beam efficiency, while a hybrid trapezoidal design provided high beam efficiency with small polarization wobble. Current fabrication versions of each are being tested, coupled to multichroic microwave kinetic inductance detectors. These planar self-similar antennas, when implemented in CMB and other detectors, could improve observations while simultaneously simplifying fabrication and detector layout.
