OEM Golf Antenna Without the antenna‚ you will have a hard time getting your radio station to come in. Since the antenna needs to be able to pick up radio waves‚ it sticks out away from the car‚ and while that helps get the signal from the stations‚ it also subjects it to possible damage since it has no protection. A trip through the carwash can break an antenna. If you need to replace your Golf’s antenna‚ then you want to be sure to replace it with a genuine OEM VW part like those found at www.vwpartsvortex

development of low cost‚ less weight‚ highly reliable‚ minimal profile antennas for wireless devices‚ it poses a new challenge for the design of antenna in wireless communications. This paper presents design and simulation of a rectangular micro strip patch array antenna at 2.4 GHz for wireless communications that provides a radiation pattern along a wide angle of beam and achieves a gain of 11.6 dBi.The rectangular micro strip patch antenna was analysed using Ansof/Ansys HFSS and also made a comparision

and due to that the signal gain is increased by three times200mW X 2 = 400mW dq2 Customer Question Describe the role of antennas in the transmission of radio waves. What type of antenna is typically used in a wireless LAN? Explain why this type of antenna is commonly used. Describe a scenario where this type of antenna may not be the best choice. What type of antenna would work best for your scenario? I need this Thursday‚ June 7th by 10 PM. Must have between 200 to 300 words. Optional

types of antennas. There are mainly two types of antennas: omnidirectional‚ and directional. Omnidirectional antennas are installed on most WLANS with AP’s that have them. Omnidirectional antennas do just what they sound like‚ which is transmit data in all directions at the same time. The signal can go horizontally and vertically; and up and down. However‚ there can be a dead spot in a minute area directly above the antenna which has no signal. One common example of this type of antenna is the dipole

types of antennas. - omnidirectional antennas: the antenna transmits in all directions simultaneously. One common omnidirectional antenna is the dipole antenna (nicknamed the “rubber duck” because of its flexibility); omnidirectional antennas transmit in all directions‚ both horizontally and vertically. The signal goes in all directions‚ as well as up and down‚ although there is often a small dead spot with no signal that is a very small area directly above the antenna. - directional antenna: As the

wireless communication using omnidirectional antennas communication is made in directions not pointing towards the recipient resulting in energy waste‚ and producing traffic collisions and reducing the battery life. One way of reducing this problem is to use of smart antenna that uses selectable radiation patterns depending on the situations. These antennas provide the ability to sense the direction of incoming signals. Smart antennas are the antenna arrays with smart signal processing algorithms

Multipath is the propagation phenomenon where transmitted information collides with ceilings‚ walls and other objects‚ which reaches the receiving antenna multiple times via different angles and at slightly different times causing a reduction in data speed and an increase in the
