A Loop-based Microstrip Dipole Antenna for Operations at 1 GHzBy Adithya Vikram Sakthivel
Abstract: This paper proposes, designs, simulates, and analyses a novel microstrip dipole antenna design consisting of two identical loops for operations for a bandwidth centering around 1 GHz (namely the 0.5 GHz to 1.5 GHz bandwidth). This proposed design consisted of FR-4 being used as a substrate of a thickness of 1.6 mm and pure copper layers of 0.1 mm in height. It should be noted that this antenna design consisted …

A Microstrip Rat-Race Coupler for Narrow-Band Operation in the X-BandBy Adithya Vikram Sakthivel
Abstract: This paper proposes, designs, describes, analyses, and simulates a novel microstrip rat-race coupler for narrow-band operations in the X-band (8 GHz to 12 GHz), namely the 9.5 GHz to 10.3 GHz sub-band. This proposed four-port passive microwave device was realized utilizing microstrip technology with pure copper (lossy) being used as a metal in the conducting layers (transmission and ground plates) and Rogers TMM6 (lossy) being used in the dielectric layer. …

A Multi-Terrain Fractal-Based Digital Camouflage PatternBy Adithya Vikram Sakthivel
Abstract: A recent need for modern infantry operations would be the requirement of an effective camouflage pattern for usage in multiple terrains. This is a result of the modern evolution of military combat as its common for military units to be rotated from one location to another (usually with drastically different ecosystems). A good camouflage pattern that has tried to address this issue would be Crye Precision’s MultiCam, however it still …

A Meandered Spiral Antenna for Operation in the X-bandBy Adithya Vikram Sakthivel
Abstract: This study proposes a wideband meandered spiral antenna based on microstrip technology for optimal operation in the X-band (8 GHz to 12 GHz). This design is based on a two-arm Archimedean spiral antenna with a coaxial feed line. This antenna exhibits good performance for operations in the X-band. This antenna was simulated with FR-4 being used as the dielectric and copper for the metallization and ground plane. This antenna was …

A Wideband 3dB Hybrid Coupler for Operations in the C-bandBy Adithya Vikram Sakthivel, Allan Kevin, Anuj Sunil, Joseph John, S Raghavan
Abstract: This study proposes and describes a novel wideband 3 dB directional coupler operating in the C-band (4–8 GHz). The proposed design was developed using microstrip technology with alumina being used as the dielectric, with a bandwidth of approximately 7 GHz (2–9 GHz), making it in theory, suitable for applications in the X-band (8–12 GHz) and L-band (1–2 GHz) as well. The increase in operational bandwidth was obtained by utilizing two …
