This Letter presents a multi‐half‐loop wideband antenna operating over a ground plane. The proposed structure has a voltage standing wave ratio <2 in the frequency range of 0.95–12.5 GHz (171%). One important attribute of this antenna is robust power‐handling, combined with a super‐wide operating bandwidth. The structure's simplicity allows robustness and easily predictable radiation properties, beneficial for several measurement systems. The antenna can be easily optimised by 4NEC2 freeware. To manufacture the antenna, only the simple mechanical treatment of metal is necessary.
