A compact asymmetric coplanar strip (ACS)‐fed ultra‐wideband (UWB) antenna for diversity applications is presented. The proposed antenna is composed of two circular radiating elements and orthogonal ACS‐fed mechanisms to achieve diversity performance across the UWB from 2.66 to 11.08 GHz, and occupies a very compact size of 28.5 × 28.5 mm 2 . By introducing a rectangular stub diagonally between the two circular radiating elements, an interport isolation better than 15 dB is achieved. Furthermore, the proposed antenna shows nearly omnidirectional radiation patterns, stable gains and a low envelope correction coefficient. The simple feeding structure, compact size and uniplanar design make it easy to be integrated within the portable device for wireless communications with diversity operations.
