Modified high frequency omnidirectional antenna for wireless communication

The need for multi band antenna are to provide simultaneous communication with multiple remote sites. This paper deals the modified Continuous Transverse Stub antenna structures for high frequency wireless Communication. Continuous Transverse Stub antenna Technology Multiband antennas are attractive for many military and commercial applications where it is required to have a single antenna that can be dynamically reconfigured on multiple frequency bands. Such antennas result in considerable savings in size and weight, as well as cost. The proposed antenna design on different Stub radius and lengths. This single antenna can radiate for three different bands. The simulation frequency range can be chosen to the range of 0.1 GHz to 13 GHz. This single antenna not only offers the multiband if provides Omni-directional radiation pattern in the horizontal plane. In this proposed structure offers 99% of total radiation efficiency in the frequency range of nearly 6.4 GHz.
