摘要

In this article, a new circularly polarized (CP) beam steering array antenna based on substrate-integrated-waveguide (SIW) is proposed for mm-wave applications. To generate a wider half power beamwidth (HPBW) and reduce mutual coupling effect a radiation element relying on zeroth order resonance (ZOR) technique has been used which has a treatment such as electromagnetic band gap (EBG) structure to have a specific structure. The antenna element can operate in a bandwidth from 33.82 to 36.37 GHz and AR bandwidth from 34.32 to 35.94 GHz. Besides, the propose element has a HPBW wider than 103, and a maximum gain of antenna is of 9.2 dBic. A 4 × 4 Butler matrix feed network based on SIW feeding technique is then designed. This feed network includes novel techniques in designing cross-over and broadband phase shifter. The synthesis of proposed Butler matrix and ZOR elements lead to a four-beam array antenna with circular polarization can cover a beam switching angles range more than 44 with a gain of 17.6 dBic.
