Özet

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.
