The trend toward personalizing vehicular radio sets has been accompanied by major engineering problems. Of these, one of the most challenging is that of designing an efficient antenna to occupy a small space. Due to these size limitations, personal radio antennas will be referred to as small antennas.

Radio frequency radiation (RFR) from radio antennas
2003 IEEE International Symposium on Electromagnetic Compatibility, 2003. EMC '03., 2003For the last 30 years, biological effects of non-ionizing radiation (NIR: 0-300 GHz) has got the top position in the scientific area, since a large population of the people are exposed to these fields. In this study, we evaluated the radio frequency radiation (RFR) at a pilot region located in Yenimahalle Sentepe Dededoruk Hill, in Ankara, Turkey ...

Radio-Telescope Antenna Parameters
IEEE Transactions on Military Electronics, 1964Principal antenna parameters which are useful in characterizing the electrical performance of radio-telescope antennas are defined and the relations between them are established. The application of these parameters to radio astronomical measurements is discussed.

Saddle antenna radio frequency ion sources
Review of Scientific Instruments, 2015Existing RF ion sources for accelerators have specific efficiencies for H+ and H− ion generation ∼3–5 mA/cm2 kW, where about 50 kW of RF power is typically needed for 50 mA beam current production. The Saddle Antenna (SA) surface plasma source (SPS) described here was developed to improve H− ion production efficiency, reliability, and availability.
