Abstract:

The paper introduces a comparative analysis of a wearable, metamaterial based 2.4 GHz microstrip patch antenna using three variants of Electromagnetic Bandgap (EBG) ground planes. A 1.8 mm thick wearable fabric (Velcro) having relative permittivity of 1.34 and tangent loss of 0.006 is used as a substrate material in the design of the conventional antenna and EBG ground planes. Three types of unit cells, namely, mushroom, slotted cross and slotted I are proposed to design the EBG ground planes. The antenna using slotted cross shape EBG as a ground plane is more compact (having 16 % reduced size) as compared to the rest of the three. The conventional antenna without EBG ground plane is relatively least efficient (77.53 %) with a gain of 8.14 dB. The same antenna if backed by a mushroom type EBG, radiate efficiently (80.92 %) with a gain of 9.63 dB in the boresight direction. The wearable antenna and EBG ground planes are designed, characterized and numerically analyzed using the Finite Integration Technique (FIT). These antennas can be used in sports, military, medical, security and rescue applications.
