Abstract :
The throughput performance of two parallel half-wavelength dipoles with different antenna spacings and antenna gain imbalances for two frequency bands in a live high-speed packet access (HSPA) network is reported. It was found that an antenna spacing of 0.25 wavelengths and gain imbalances of up to 6 dB are sufficient to provide significant throughput gain for the same transmit power, or equivalently, an increase in network coverage for a given throughput, as compared to a single dipole.
