A directional coupler typically has four ports: an input, an output, a coupled port, and an isolated port. Overview of Directional Couplers Directional couplers are one of the most frequently used components in radio frequency systems that enable the measurement and diversion of power without disturbing the original signal flow. They are exceptionally accurate in […]

Horn antennas operate at higher frequencies (2-40 GHz) with greater directionality and gain (10-20 dB) compared to omnidirectional dipole antennas (1 MHz-1 GHz, 2.15 dB gain). Dipole Antenna Structure and Design A dipole antenna consists of two identical conductive elements such as metal wires or rods, which are bilaterally symmetrical. The antenna operates most efficiently

To achieve complete coverage with a minimum s-band antenna gain of -7 dBi, a straightforward configuration utilizing dual circularly polarized microstrip patch antennas was employed. The configuration involved the implementation of a wide bandwidth, dual circularly polarized truncated corner microstrip antenna, which was complemented by two parasitic patches. To enhance the cross polarization bandwidth, diagonally embedded holes
