How are antennas represented in TPC schematics?

In TPC schematics, antennas are effectively represented by a vertical line that is often flared out at the top. This representation conveys both the physical structure and operational characteristics of antennas in a simplified manner, allowing for quick recognition within a schematic. The flared top signifies the area where the electromagnetic waves are radiated or received, capturing the essence of how antennas function. This visual representation helps engineers and technicians easily identify antenna components within electronic systems or communications layouts, facilitating better understanding and design development.

Other choices, while they might represent different components in various contexts, do not accurately depict how antennas are standardized in TPC schematics. For example, diagonal lines or circles with emanating waves might be used for different types of signals or components but do not encapsulate the specific form and function of antennas as clearly as the depicted vertical line with a flared top.
