An optimum downtilt angle has been evaluated for numerous practical macrocellular site and antenna configurations for electrical and mechanical antenna downtilt concepts. Optimum Antenna Downtilt Angles for Macrocellular WCDMA NetworkÄirectory of Open Access Journals (Sweden)įull Text Available The impact of antenna downtilt on the performance of cellular WCDMA network has been studied by using a radio network planning tool. The directivity was 14.7 dB, while the gain was 8.1 dB. Experimental results inX-band, in good agreement with the theory, show that it is possible to scan the main lobe an angle ofpm30degby a variation of the frequencypm300MHz, and where the 3 dB beamwidth is less than10deg. This gives a scan of the main lobe due to the phase-shift in the resonator in addition to that created by the transmission line phase.-shift. ![]() ![]() The principles of using radiating microstrip resonators as elements in a frequency scanning antenna array are described.
