Stacked E-shaped patch antenna for lower-band ultrawideband (UWB) applications

In this research paper a design of Microstip patch antenna for the ultra-wide band (UWB) applications is presented. Ultra wide band antennas has very wide band of operation which accommodates many communication frequencies as set by the federal commission of communication. The UWB antennas is based on the micro strip patch antenna concept and the design of the antenna is based on the stack antenna or multi-layer antenna. Stacking is used in designing for increasing the bandwidth of the antenna so stacking concept is good for the designing of the UWB antenna. The feeding used to feed the antenna is micro strip line feed. Micro strip line feeding technique is one of very popular feeding technique to feed the antenna because its fabrication is very simple. The proposed design is simulated in the CADFEKO software which is very useful for the design and analysis of a wide range of electromagnetic problem. It has many applications to simulate 3D electromagnetic circuit included antenna design, micro strip antenna and circuits. The simulation results shows the antenna bandwidth of 13.9 GHz from 2.6 to 16.5 GHz. So we can clearly say that the antenna is ultra-wide band in nature.

AbstractIn this paper, a miniaturized microstrip patch antenna using a negative index metamaterial with modified split-ring resonator (SRR) unit cells is proposed for ultra-wideband (UWB) applications. The new design of metamaterial based microstrip patch antenna has been optimized to provide an improved bandwidth and multiple frequency operations. All the antenna performance parameters are presented in response-graphs. Also it is mentioned that the physical dimensions of the metamaterial based patch antenna are very small, which is convenient to modern communication. A 130 % bandwidth, covering the frequency band of 2.9–13.5 GHz, (for return loss less than or equal –10 dB) is achieved, which allow the antenna to operate in the Federal Communication Commission (FCC) band. In addition, the antenna has a good radiation pattern in the ultra-wide band spectrum, and it is nearly omnidirectional.
