Several horn antennas designed to operate at various frequencies including ISM bands (433 MHz, 0.9, 2.5, 3.5 and 5 GHz) and 1.8 GHz, respectively, are discussed. The preliminary construction of these antennas was firstly implemented through numerical computation using the available HFSS 11 optimizer tools. The optimization process was done by simply varying the size and angle of flares. The best design...
Yagi-Uda antennas are commonly used for data communications. Link budgets are calculated to ensure adequate fade margin. The presence of adjacent conducting material can affect antenna gain and impedance matching. Numerical modeling demonstrates that the gain of a 12 element Yagi-Uda is degraded by more than 2 dB when a human model is located in close proximity to the rear of the antenna. There are...
