A wideband low‐profile planar square segmented loop antenna for unmanned aerial vehicle (UAV) applications is proposed. The antenna consists of a square segmented loop, a patch element, and a shorting strip. The antenna operates at 956 MHz because the eight segments of the loop are electrically connected by capacitive coupling. By adding the patch element and shorting strip, the antenna has a wideband covering GPS L1, GSM1800, GSM1900, UMTS, LTE2300, LTE2500, and 2400 MHz ISM bands due to improved impedance matching. The antenna has omnidirectional radiation at 956 MHz and quasi‐omnidirectional radiation over the broad bandwidth.
