“…The compact size is significant in head imaging applications. By and large, there are generally two methods for designing a wideband antenna: (a) utilizing slot-loaded collapsed dipole [6][7][8] and (b) utilizing patch or monopole. 9 Li et al 7,8 researched with some artificial magnetic conductor (AMC) reflector-based dipole antenna configurations.…”

“…By utilizing the AMC reflector, the surface height may be halved compared to the perfect electrical conductor (PEC) equivalent. A dipole configuration stacked antenna arrays is reported in Li et al 6 The stacked configuration has the advantage of taking up less space in the aperture. The efficiency and the performance of an antenna can be increased by various methodologies like a slot(s) on the patch and slot(s) embedded on the ground plane.…”

This paper introduces a lightweight wideband planar antenna with an antenna array configuration for microwave head imaging. The designed antenna is composed of a double hollow rectangular-shaped patch and with the slotted ground. Its measurements are small: 0.28λ Â 0.24λ Â 0.006λ, where λ is the lowest operating frequency's wavelength. The design process has been completed using CST and then fine-tune the parameters of the architecture structure to accomplish the ideal bandwidth. The antenna is manufactured and measured in order to test antenna properties. The prototype was being used for brain screening than with the Hugo-head model. With adequate impedance matching, the antenna meets an operational bandwidth of 1.82 GHz (1.22-3.04 GHz) with an overall peak gain of 5 dBi with a stable radiation property.Fidelity factors both for face-to-face and side by side alignment are 92.7% and 83.75%, respectively, indicating that the antenna had a little signal interruption. To determine the backscattered signals of the antenna with Hugo-head phantom, a nine-antenna array-based setup is assumed, with one antenna serving as a transmitter and the remaining eight receiving the dispersed signals.

“…13 The second form is sandwich structure applicable for the high frequency ratio. [17][18][19] The design implements a dual-band antenna operating at 0.69 to 0.96 GHz and 3.5 to 4.9 GHz by introducing a frequency-selective surface with filtering properties between higher and lower bands. 17 In other designs, four metal pieces are introduced between higher and lower bands to provide capacitive loading for lower band (LB) and ground surface for higher band (HB).…”

A compact dual-band antenna is designed in this paper, which consists of a pair of lower band (LB) element and four higher band (HB) elements operating at 0.69 to 0.96 GHz and 3.3 to 3.6 GHz, respectively. Four HB elements are put between the adjacent dipole arms of LB element. All of elements are at the same height, and having their own reflector. A designed dual-band dualpolarized antenna at high frequency ratio will be fulfilled without added any other structure. The fabricated antenna sample has been measured, results show that the average gains of LB and HB elements are 8.48 dBi and 8.44 dBi and the half power beam widths are 69.1 ± 9 and 60.7 ± 8.5 , respectively. Moreover, dual-polarized property of both LB and HB is checked. The crosspolarization discrimination values are greater than 15 dB. The proposed antenna is implemented the coverage of two bands with high frequency ratio with a simple structure, and the antenna with both low profile and high gain characteristics. All of the results demonstrate that the antenna radiation boasts its favorable performance and can be a good candidate in 5G mobile communication system for sub-6 GHz base stations.

“…An antenna array can be backed by artificial magnetic conductor (AMC) or perfect electric conductor (PEC) as a ground plane. The use of AMCs has been studied for the size reduction of antenna height as compared with PECs for different frequency bands 18–21 . Despite of the fact that MSs have a broad range of applications but controlling and manipulation the polarization state of electromagnetic (EM) waves have attracted a great interest of research community.…”

Summary A dual broadband cross‐polarization‐conversion (CPC) metasurface is designed, simulated, fabricated and results are experimentally verified. The designed patch of metasurface unit cell is composed of a triangular loop connected with two arcs at both ends. The metasurface is made of 44 × 44 unit cells arranged periodically on 1.6‐mm‐thick FR4 dielectric substrate, backed by a metallic copper sheet as a reflector surface on the back side of the dielectric substrate. The surface achieves CPC in two bands (7–8.5 GHz) and (13–19 GHz), in the microwave regime. The simulation results show that the polarization conversion ratio (PCR) is almost 90% for both x polarized (TM) and y polarized (TE) electromagnetic (EM) waves. The proposed metasurface is fabricated on 308 × 308 mm2 FR4 substrate plane. The simulated results are validated and are found in close covenant with the measured results.
