The antenna is a receiver’s component that collects electromagnetic waves from various directions. The rationale behind focusing on the circular array is that its tuning ensures that the receiver processes the desired signal only, while rejecting the unwanted interference. This can only be achieved by a directional external antenna that is large in size and must be steered mechanically in the desired direction. As this arrangement is not practical, smart antennae have been proposed as an alternative. A circular phased array can produce a predicted radiation pattern, whereby it receives maximum energy from the desired direction without the need for mechanical control. Owing to these characteristics, phased arrays exhibit high gain as well as immunity to interference, making them ideal for use in high interference environments. This combination would ensure that it could be incorporated into a commercial deck receiver or installed on vehicles.
