“…Consequently, considerable research efforts have been made towards the miniaturisation of UWB antennas and various miniaturisation techniques have been thus tried to design compact UWB antennas [6][7][8][9][10]. For example, a small UWB antenna adopting a half circular quasiself-complementary structure together with a notch on the microstrip feedline has been proposed and studied [9].…”

Brain Stroke is the leading cause of disability and death in the world in which the supply of blood to the brain is stopped by a clot or burst of blood vessel. Microwave techniques have been investigated as a reliable solution for the immediate detection of brain strokes. To that end, an appropriate signal acquisition and processing method is needed to detect the damaged tissue using the extremely weak back scattered microwave signals from the imaged head. In that regard, a frequency domain method integrated with a multi-static ultra wide band antenna array is proposed. The utilized array comprises 24 tapered slot antennas which are located around the head to collect the back scattered signals in a multi-static mode. An image reconstruction method based on Mathieu function is utilized to predict the scattered electric field and power inside the elliptical shape imaging region. The system's configuration, imaging method and obtained results are reported in this paper.Index Terms -Brain stroke detection, tapered slot antenna, microwave imaging, Mathieu function.

“…Various miniaturization techniques have been adopted over the past few decades to develop compact UWB antennas whilst maintaining antenna performance [11][12][13]. Top loading the back side of a microstrip fed elliptical monopole antenna [13] has led to miniaturized physical size of 25 mm X 26mm.…”

In this paper a compact elliptical disc monopole antenna with tapered microstrip feed line for UWB application is proposed. The antenna is designed using the quasi self-complementary technique for attaining electrical as well as physical size reduction. A triangular notch is included in the ground plane for impedance matching between the antenna and the RF front end. The adoption of this miniaturization technique has narrowed the impedance bandwidth of the antenna in the UWB range but lead to an additional operating bandwidth in Ku band thereby exhibiting dual band behavior. This reduction in the bandwidth in the UWB range was overcome by using the tapered microstrip feed line configuration. The antenna exhibited a wide impedance bandwidth extending beyond the UWB range and hence could be used for both UWB as well as Ku band applications. The antenna has a physical dimension of 16mm X 25mm corresponding to an electrical size of 0.24λ and was designed on an FR4 substrate with εr of 4.7. It is seen that the antenna proposed here has led to 62% size reduction with a percentage impedance bandwidth of 123.46% when compared with the conventional elliptical disc monopole antenna.
