Isotropic Radiators

TL;DR

The paper presents two antenna designs capable of isotropic radiation patterns by utilizing elliptically polarized radiation, challenging the notion that isotropic radiation is impossible.

Contribution

It introduces novel antenna examples that achieve isotropic radiation through elliptically polarized waves, circumventing the hairy-ball theorem.

Findings

Demonstration of antennas with isotropic radiation patterns

Use of elliptically polarized radiation to evade topological constraints

Challenging the assumption that isotropic radiation is impossible

Abstract

We give two examples of antennas with isotropic radiation patterns. Because these involve elliptically polarized radiation, they evade the "hairy-ball theorem" that suggests isotropic radiation would be impossible.
