It is designed on a polyimide substrate with dielectric constant of 3.5, tangent loss of 0.006, and thickness of 10 mu m. It consists of two rectangular patches fed through the Coplanar Waveguide (CPW) feeding technique. It also combines transverse and longitudinal slots on the rectangular patches to create circular polarization and improve the open stop-band issue of the LWAs. In addition, a matching element is utilized at each feeding, and then the feed line is cut by H-slots to improve the mutual coupling of the antenna. The proposed antenna offers a wide Bandwidth (BW) of 110- 135 GHz with small dimensions of 6 x 7 mm(2). The main beam scans from -87 degrees at 110 GHz to 0 degrees at 130 GHz. The simulated peak gain of 14.8 dBic is obtained in an almost broadside direction at 115 GHz.eninfo:eu-repo/semantics/closedAccessLWAMIMOD-BandFlexible Transparent AntennaAIPOther9094WOS:000893084900019N/A10.1109/MTTW56973.2022.9942584
