It has bristles or sensers on the antenna. It depends on what bug.
An antenna picks up waves by converting electromagnetic fields into electrical signals. When radio waves interact with the antenna, they induce an alternating current within the antenna which is then processed by the connected circuitry to extract information or energy from the waves. The size and shape of the antenna determine which frequencies it is most sensitive to.
Antennas pick up waves through a process called electromagnetic induction. When an electromagnetic wave passes through an antenna, it generates a small electrical current in the antenna which can be detected and amplified to recover information encoded in the wave. The size and shape of the antenna determine the types of waves it can efficiently pick up.
Faraday's law of electromagnetic induction explains how an antenna picks up a radio signal. When a varying magnetic field from the radio signal interacts with the antenna, it induces an electric current in the antenna through electromagnetic induction. This current can then be amplified and decoded to produce the audio signal heard on the radio.
He generated electromagnetic waves by accelerating charges back and forth rapidly in an antenna. He detected the waves by using a similar antenna that would convert the electromagnetic waves into electrical signals.
Electromagnetic waves, such as radio waves, transmit information from one antenna to another. These waves carry the signal that contains the information being transmitted, like radio broadcasts, Wi-Fi signals, or cellular communication.
The oscillating electrical current in the antenna causes the electrons in the antenna to accelerate back and forth, creating electromagnetic waves that propagate as radio waves. This motion generates a changing electric field that propagates through space at the speed of light.

No, radio antennas only pick up electromagnetic waves. Ultrasound is mechanical pressure waves, you need a microphone to pick them up.
The antenna of walky talkies are vertical when in position, so to better pick up radio waves more accurately.
They are picked up by the antenna.
Yes, a UHF antenna can pick up VHF signals, but not well. The size difference makes the uhf antenna "inefficient" for the longer vhf wave length, but some energy can be received by the uhf antenna.

An antenna picks up radio waves and converts them to electrical current
Your VW Passat stereo will not pick up any radio stations if the antenna has come loose. The retractable antenna may also be stuck in the down position which severely limits its ability to pick up stations.
they use radio waves to pick up some what satellite images or existance of things in space
