Multimode Textile Array Antenna for Millimeter Wave Wearable Applications

Abstract

The development of a multimode textile array antena for wearable applications is discussed in this study. For fabrication, copper sheet and conductive copper materials are employed. Because the body wear antenna is intended to function close to the human body, it should be lightweight and low profile. The performance of the suggested antenna is examined for different textile materials, which serve as its substrate. Additionally, a 1 x 4 antenna array is made to increase gain and bandwidth. According to the results, the designed antenna has high gain and directivity of 14dB and 10dB, respectively. Future 5G wireless devices may employ the frequencies obtained—27.08GHz, 30.16GHz, 38.62GHz, and 45.59GHz—as well as the reflection coefficients—-24.57dB, -13.735dB, -23.61dB, and -10.912dB, respectively. An excellent radiation pattern, good gain of 10.35 dB, and high directivity of 14.206 dB are all shown by the suggested patch antenna. Due to its very low profile, the antenna architecture is easily adaptable to systems where limited space is a major consideration. The antenna may be used for wearable applications and will be efficient for the next 5G applications since it is made of cotton.
