For dual-band operation, the folded meta-inspired antenna may operate as a folded monopole at a higher frequency band and operate as a slot-type radiator at a lower frequency band. The plurality of resonances may cause the folded meta-inspired antenna to achieve broader bandwidth at both lower and higher frequency bands.Type: ApplicationFiled: December 3, 2012Publication date: June 5, 2014Inventors: Debabani Choudhury, Ana Yepes, Vinay Gowda
