Abstract
This paper proposed a differential bowtie antenna which can be directly integrated to a system-on-chip (SoC) ultra-wideband pulse radar module which will be used in sense and avoid applications for drones. Proposed antenna is very compact with a total size of 17 x 12 x 1.25 mm. Reflection coefficient of the antenna, |S11|, is less than -10dB between 6.1 GHz and 10 GHz, corresponds to percentage bandwidth of 48%. Also, it is exhibiting very high radiation efficiency over the operating bandwidth. Moreover, it has very stable and uniform radiation pattern in all frequencies, which is leading good time domain behavior. 10 This miniaturized antenna with differential feeding exhibits constant gain over the frequency bandwidth, while having broadband operation. Therefore, in this paper, a UAV antenna satisfying all of the requirements of a sense and avoid radar according to integrate to current MMICs is presented.
