In this letter, we present a compact four-element superdirective antenna array operating at 900M Hz frequency band. In this antenna, only one element is excited while the others are parasitic-loaded elements. The antenna total dimensions are 231 × 122mm 2 and it has a total directivity of 11.6dBi and radiation efficiency of 46%. This antenna is significantly compact compared with others presenting the same directivity.
