Small end‐fire superdirective folded meandered monopole antenna array

In this letter, we present a compact four‐element superdirective antenna array operating at 900MHz frequency band. In this antenna, only one element is excited while the others are parasitic‐loaded elements. The antenna total dimensions are 231 × 122 mm2 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. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2122–2124, 2016
