RHOMBIC ANTENNA

You know......Thereare different types of antennas like  V antenna, INVERTED V antenna, RHOMBIC antenna, HELICAL antenna, LONG WIRE antennas, TRAVELLING WAVE antennas etc.....One of most popular one is the RHOMBIC antenna. Now we can briefly study about this antenna.
              

PATTERNS

    It is constructed with two inverted v antennas or two v antenna at obtuse angles. It is the most commonly used antenna in most of the radio communications part if it has sufficient place to install it. It is used in point to point communication. The total gain of the antenna is based on the axis that is from feeding point to terminating resistance.  If the impedance is equal to the total characteristic impedance , then the gain will be more. At the terminating resistor  half of the power will be completely dissipated where the remaining is radiated. The resistance of the terminating resistance should be in between 600-800 ohms. But we cannot use wire wound resistance in this case, because wire wound resistance is highly inductive in nature...but we need resistance with zero inductance and slight capacitance. So we use open wire feeder which offers 600 ohms. The radiation pattern is uni directional in nature. If we want to change it to bi directional we need to remove terminating resistance. The power disipation at resistance is 35-50% , its directvity is 20-90 and its power gain is 50-60. we can design te rhombic antenna also. This is about rhombic antenna.

Antenna.......What is an antenna?

First of all we can learn the basic definition of an antenna. An antenna is an Ariel working between free space and the transmitting end and it acts also between the receiver and the free space. In the place of free space we can say wave guides also. Wave guides are one form of guiding structures......There may be number of antennas in this developing world....But the basic antenna starts from a single wire and double wire antennas only....An antenna can also change the light energy in to electromagnetic waves...em waves are nothing but the waves which contain electric and magnetic fields....In the antenna and wave propagation theory there are many many lots and lots of bundles of information about antennas....Because through these wonderful structures only world is communicating in the mean that people are communicating....In the next posts i will clearly explain the basic structures of antennas which could be very useful for exciting minds of electronics and communications....

Hi Friends.....!!!!!

First of all before introducing myself i want to quote that i am blessed to be human who rules the world......I am yamini pursuing my  b tech. I have a strong desire to create a blog which act as a source of electronics.I try maximum to publish each and every concept in detail from electronics.Please give your valuable suggestions and we all together can help the people who had  some desire to learn....bye friends... .
