In this article, a planar antenna with quasi‐isotropic radiation pattern is proposed for applications in drone communication. The proposed antenna consists of top‐loaded monopole and slotted loop antennas. The top‐loaded monopole provides a monopole‐like radiation pattern with a planar profile. To compensate for nulls in the monopole radiation pattern, a slotted loop antenna is added. Therefore, when two radiation patterns are combined, a quasi‐isotropic pattern is achieved with a low profile thickness of 7.2 mm. The performance of the proposed antenna is verified by simulation and experimental results. The antenna's 10‐dB impedance bandwidth is in the range of 2–2.4 GHz. The quasi‐isotropic radiation pattern is verified from both simulation and measured results.
