Metamaterial assisted hybrid response from frequency selective surface roll off and leaky wave resonator integrated antenna for underground applications

In emerging era of wireless technologies such as cognitive radio, wireless sensor networks etc., designing effective low frequency antennas < 1000 MHz and specifically < 700 remains a significant challenge due to its poor (often negative) gain and severely limited bandwidth (≈ 1%), despite exhibiting fair radiation p...
