In this work, we have analyzed the tradeoffs between the beamwidth of the antenna radiation pattern and the effect of the time and angular dispersion of the radio propagation channel on the bit error rate (BER) performance in an OFDM scheme. We have considered a line-of-sight (LOS) scenario and a transmitter antenna with different radiation width patterns. The fade depth, the received power distribution, and the delay spread have been calculated as a function of the angle width of the antenna radiation pattern. Simulations results show that QPSK modulation scheme is more sensitive to variations in the beamwidth than a 64QAM scheme. Moreover, for QPSK we can get better BER using a narrow beamwidth, but in this case tracking the antenna direction becomes necessary, whereas for 64QAM we get worse BER but we can use a wide beamwidth and relax the requirements for tracking the antenna direction.
