On-Body V-Band Leaky-Wave Antenna for Navigation and Safety Applications
Résumé
The paper discusses an on-body V-band leakywave antenna for navigation and safety applications. The antenna is based on meandering microstrip line operating in V-Band with continuous beam scanning from backward-toforward direction in the elevation plane. The width of the transverse line are alternatively varied to remove the open stop band (OSB) at the broadside frequency. The final antenna shows a scanning range in the elevation direction from -45 degrees to 50 degrees with no impact on performance at broadside direction. The antenna has a gain of more than 11 dB across the operating frequency range. The structure is simulated and the results and compared with the other leaky-wave antenna designs. The performance of the antenna is also verified for on-body conditions. The antenna is self matched at 5011 hence removing the need for matching circuit. The requirements for an on-body antenna are also analysed for the designed structure.
