This paper looks toward theoretical and practical aspects of a new 2-D direction finding method. It promotes a new idea for multichannel azimuth estimation based on amplitude difference of a signal acquired on adjacent antennas. The essence of the method is a simple hardware consisting of small size microwave (7–19 GHz) antennas equipped with amplitude detectors, frequency synthesizer, low power mixed-signal...
The resonant frequencies of a microstrip patch antenna are dependent on the dielectric constant of its substrate and the physical dimensions of its radiation patch. Both of these parameters are temperature-dependent. In this paper, we investigated the effects of temperature on the antenna resonant frequencies for the purpose of studying the microstrip patch antenna as a temperature sensor. First,...
