For recording yourself, you should choose a cardioid pattern
, which means that it records what it's aimed at very well and it depresses the ambient noise from all other directions.
Wright, "A compact flush-mounting antenna with direction finding and steerable cardioid pattern
capability," IEEE Trans.
With the four receiving antennas (N = 4) in a cardioid pattern
, we rotated the beam direction in increments of 90[degrees] for each antenna and entered the characteristics into the receiving connection matrix [A.sub.RX] (see Figure 13, Case III).
Better still, the Yeti Pro offers four recording modes - omni-directional, cardioid pattern
, stereo and a bi-directional.
If there are several symmetrical pairs of outside antennas, switching among the pairs causes the cardioid pattern
to rotate, allowing calculation of the DOA of the signal.
The TEM feed is terminated at the reflector's surface by a matching structure that maintains a cardioid pattern
at low frequencies.
This excitation not only yields the cardioid pattern
, but produces near-constant image impedance.
