Patch antenna loaded with C-DNM for X-band applications
This paper proposes patch antenna for X-band [8.2 GHz; 12.4 GHz] and military applications, enhanced by double negative metamaterial complementary (C-DNM) cells. Two different structures will be presented and discussed, which involve: (1) C-DNM with square patch antenna, and (2) C-DNM with circular patch antenna. The antenna was designed with resonance frequency around at 12 GHz. The metamaterial substrate has a potential to maintain the amplitude of the reflection coefficient at the specific resonant frequency as well as increase the directivity gain and/or the bandwidth. The focusing parameter is to achieve a better directivity gain and wide radiation pattern that obtained from a structure with several cells C-DNM for circular patch antenna. The simulations show that the addition of C-DNM to circular patch antenna provides better performance in terms of directivity 7.45dB to 7.88dB for circular patch. For square patch; the antenna is contributing the best reflection coefficient value than −40.36 dB and value of 7.74 of directivity gain.
