Novel miniaturized BDS dual-band antenna based on composite right/left-handed substrate integrated waveguide

A novel miniaturized Beidou satellite navigation system (BDS) dual band antenna based on composite right/left-handed (CRLH) substrate integrated waveguide (SIW) is proposed in this paper. The interdigital slot etched on the SIW surface make the CRLH resonator, so that the antenna radiate on negative order resonance. Performance has been proved the antenna cover the BDS B1I and B2I band with a high gain. Both simulation and measurement results are given respectively.
