A novel microstrip-fed metamaterial-inspired antenna is proposed for implantable applications. The designed antenna operates in the Industrial, Scientific and Medical band at a frequency (2.4-2.5) GHz. The implantable antenna comprises of two split ring resonators. The use of metamaterial not only dramatically reduces the size of the antenna, but also improves its gain and bandwidth. Different methods of size reduction with optimum gain and bandwidth are here discussed in detail. The implantable antenna is designed using FR4 substrate which provides better gain, miniature size (84% size reduction), good impedance matching, circular polarization with 3.41% of 3-dB axial ratio bandwidth. Circularly polarized antennas are usually preferred as they reduce polarization mismatch loss. The antenna is 29 × 28 mm 2 in size with 4.86 dB gain and 140 MHz impedance bandwidth. The design of phantom liquid, the computation of its pH value, and measurement of its permittivity are thoroughly reported. The permittivity of the liquid is found to increase with the pH value. The permittivity of phantom liquid has been validated with 85070E dielectric probe kit. A detailed description of different probes is provided. The measurement results are in good agreement with simulations. Finally, the design of phantom for implantable applications and techniques for size reduction of the same have been described. This reduced size will help to fit antenna in medical devices, providing greater ease for the body movement.

“…The advantages of monopole antennas are low profile, cheap cost, broader band operating bandwidths and easy structure. A simple printed three slot antenna structure having the arms with lengths is reported to the CP operation [3]- [4]. The CP operation and principle may be achieved by generating TM11 modes that are 90 o phase.…”

In this article, a novel microstrip patch textile antenna is to be designed for wearable applications. The designed antenna has the design parameters of the size is 90 × 70 × 1.57 mm3 and the substrate is Jeans cloth whose dielectric constant is 1.6. The proposed antenna can be operating the resonant frequency at 2.45 GHz with a return loss of −20 dB. The proposed antenna has a gain of 2 dBi and VSWR is around 1.4 at the resonating frequency. This proposed novel antenna can be used in military jackets, because of its merits like compatibility, more flexible in designs and shape, excellent performance at different bending angles, human safety, miniaturization, power consumption etc.
