Adjusting Radiation Pattern of Small Antennas [PDF]
2020 International Workshop on Antenna Technology (iWAT), 2020 The antenna clusters have been used to control the impedance properties of the antenna, but they have potential also in radiation pattern reconfigurability. We demonstrate the benefits of multi-feed antennas using a mobile antenna as an example.

Embedding Information in Radiation Pattern Fluctuations [PDF]
2020 IEEE International Symposium on Information Theory (ISIT), 2020 The radiation pattern of transmit antennas varies and fluctuates as receivers change their location, other objects move around, and due to the antenna design itself. In this paper, we demonstrate how this observation can be exploited to align most of the interference signal power and significantly increase the average achievable communication rates ...

Modeling the radiation pattern of LEDs
Optics Express, 2008 Light-emitting diodes (LEDs) come in many varieties and with a wide range of radiation patterns. We propose a general, simple but accurate analytic representation for the radiation pattern of the light emitted from an LED. To accurately render both the angular intensity distribution and the irradiance spatial pattern, a simple phenomenological model ...
