This randomized trial demonstrates the effectiveness of a miniaturized antenna in ultrawide band applications, indicating its potential for wireless and medical uses.
A miniaturized Antipodal Vivaldi Antenna (AVA) based on linearly flared radiating fins for wireless and medical applications is proposed. The proposed design uses an FR4 substrate with a linearly flared microstrip patch AVA in ultrawide band (UWB). Furthermore, the compactness of the design is achieved by using the innovative linearly flared radiating fins, which can be viewed as a performance enhancer. An antenna operates in the frequency range of 3.1–10.6 GHz. It is designed, fabricated, and measured over the entire UWB spectrum. The size of the proposed antenna is 50 × 32 × 1.6 mm3 (0.516λ0 x 0.331λ0 x 0.016λ0 at 3.1 GHz). The antenna exhibits a measured peak gain of 13.71 dBi at 10.6 GHz and a spectrum average gain of 7.61 dBi. The proposed antenna achieves a % fractional bandwidth of 174%, which is higher than that of most reported AVAs while occupying a smaller electrical volume. Experimental studies show stable performance and radiation parameters, which indicate that it has potential application for wireless and medical applications.
