Log Periodic Fractal Koch Antenna for Uhf Band Applications
In this paper, the design of Log Periodic Fractal Koch Antennas (LPFKA) is proposed for Ultra High Frequency (UHF) band applications. The procedure to design the LPFKA with three different numbers of iterations in order to reduce the antenna size is discussed. The Computer Simulation Technology (CST) software has been used to analyze the performances of the designed antennas such as return loss...
متن کاملBroadband and Low Profile Antenna for Uhf Band
The requirement of wideband and compact devices is ever increasing in most communication systems. In addition, recent increases in the transmission and reception of information have created a need for broadband and low profile antennas. This necessity is particularly challenging in designing Radio Frequency (RF) products that demand these features at low RF bands. There are numerous situations ...
متن کاملTruncated Rectangular Microstrip Antenna for Wide band
-Wide band truncated rectangular microstrip antenna with H slot loaded and defected ground plane structure is presented in this paper to increase the bandwidth. It is found that the impedance bandwidth of a microstrip antenna could be enhanced considerably when a defected ground structure is used .The band width of a truncated rectangular microstrip antenna with H slot is 21.2% whereas after ad...
متن کاملFM wide band panel dipole antenna
It is very common that when a broadcaster needs to install an FM transmitting antenna within a large metropolitan area he places it on the tallest structure or building available. When the rooftop is already occupied by a large number of other types of transmitting and receiving antennas, the panel dipole antenna should be chosen. This antenna is secured to the side walls of the upper floors wi...
متن کاملWide Band CPW Fed Slotted Microstrip Antenna
In this paper, a design of compact coplanar waveguide fed UWB slot antenna is presented. The proposed antenna has simple structure consisting rectangular slot with uneven coplanar ground structures. The proposed antenna structure is investigated by using MoM based electromagnetic solver IE3D. The simulation and measured results show that the antenna offers performance for wideband system from 4...
