Abstract A low‐cost, small‐size, broadband antenna array of Archimedean spiral elements is designed with beam‐steering and interference‐nulling capabilities for mobile platforms (for example, laptop computers). Its adaptive beam‐forming and beam‐steering capabilities are investigated using two well‐known techniques; the finite‐difference time‐domain (FDTD) method and the method of moments (MoM)‐based numerical electromagnetic code (NEC2). Although the structure is optimized for 3 rd ‐generation GSM and Bluetooth applications (that is, around 2.5 GHz), it is illustrated that this structure may also be used to cover all radio/TV broadcast (from FM radio to UHF TV stations) and up to several GHz frequencies that are reserved for future applications. © Wiley Periodicals, Inc.
