This research details the design and analysis of a novel miniaturized microstrip wearable antenna, loaded with metamaterial for breast cancer detection. The proposed antenna is printed on Arlon Diclad 1000 with a dielectric constant value of 10.2 that exhibits triple-band resonance at 2.4 GHz, 5.5 GHz, and 6.1 GHz and it also provides a gain of 4.3208 dB at 2.4 GHz, 1.92 dB at 5.5 GHz. The total dimension of the antenna is 5.64 cm × 5.58 cm and the thickness is 3. 175 mm. A metal ring of 2.69 mm is covering the outer part of the antenna which reduces Specific Absorption Rate and also provides mechanical rigidity to the structure against bending and warping conditions. Spiral Array Metamaterial design is used to reduce the dimension of the antenna to make it suitable for wearable medical imaging applications. Performance analysis of the proposed antenna was done by keeping the antenna near to normal breast and tumorous breast phantom which utilizes GPR algorithm to determine the depth of tumour, which can be seen in the migrated image. Numerical tests were performed to assess the impact of various tumour sizes (2 mm, 3 mm) and the simulation results were presented to validate the utility of the proposed design in terms of return loss for early-stage breast cancer detection.
