Slot antennas are used for their ability to provide a very directional signal (transmitted) with negligible signal lobes in the direction other than that which the slot is facing.

The size of the dish isn't as important as the length of the antenna. The antenna is INSIDE the little can at the focus of the dish. The length of the antenna is tuned to the wavelength of the frequency being received.
Attached the wiring harness and the antenna cable to the back of your stereo. Slide the stereo into the stereo slot. Tighten the stereo with the stereo retaining screws.
The power radiation pattern represents how the radiated power from an antenna is distributed in space. It shows the strength of the radiated power in different directions relative to the antenna. This pattern helps to understand how an antenna radiates energy and is important in designing and evaluating antenna performance.
Connect the wiring harness and the antenna cable to the back of the new radio. Slide the radio into the radio slot. Secure the radio with the retaining screws.
Hertz Antenna is lambda by 2 antenna & marconi antenna is lambda by 4 antenna...
There are three features of the iPhone 4 that could be described as slits. One such feature is the SIM card slot. This is located on the right-hand side of the antenna (the metal band on the side of the phone). The SIM card of an iPhone 4 can be inserted into and removed from this slot. Another such feature is located next to the front-facing camera. It is a speaker, which provides enhanced volume when taking calls. Another 'slit-like' feature is located on the bottom-part of the antenna. This slot is where the connector cable is to be inserted, and is used when connecting the iPhone 4 to a variety of devices, such as computers, chargers, and speakers.
A satellite antenna has one very important purpose. It is designed to allow a home to receive a satellite signal, which then allows users to receive a television signal.
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
A passive antenna is an antenna that is not powered by an amplifier.
