In this paper, we present a dual-frequency, square spiral microstrip patch antenna constructed from Multi-Walled Carbon Nanotubes (MWCNT) ink deposited on a thin flexible FR4 substrate using a cold printing process. The proposed antenna operates at 1.2276 GHz for wearable Global Position System applications and 2.47 GHz for wearable Multichannel Multipoint Distribution Services. CST Microwave Studio (CST MWS) was utilized to evaluate the return loss, matching impedance, resonant frequency, bandwidth, and far-field radiation patters. The antenna gain is found to be -12.5 dBi and -4.25 at 1.2276 GHz and 2.47 GHz, respectively. An excellent agreement was found between the measured and simulated results.
