This letter discusses the effect of antenna losses due to rain on a 26 GHz microwave link and the technique of extracting the losses from the measured rain atten-uation. A 2-feet parabolic dish antenna with horizontal polarization has been used in the study. The measurement results have been compared with those obtained from other locations in Malaysia and(More)
The results of rain attenuation on terrestrial microwave links in a tropical climate has been reported in this paper. The results are presented in the form of rate of change of attenuation with respect to rain rate, denoted by S.R %p /. This is in turn used for predicting the expected rain attenuation at any %p of the time rain rate is exceeded in any(More)
— This paper proposes solution to optimize the peak side lobes level (PSLL) in a distributed random antenna array (RAA) when locations of the nodes in the array cannot be manipulated. Using the conventional beamforming method, RAA produces a poor beam pattern with high sidelobe level, which greatly reduces the performance and the efficiency of the antenna.(More)
