In this paper, planar monopole antenna for wireless applications with triple band has been proposed. It simply consists of hexagonal meander-line structure and defected ground plane, which occupy a small PCB area of 50
An ultra-wideband slotted microstrip patch antenna has been proposed in this paper for uplink and downlink satellite applications in c band of IEEE 802.11 standards. Various slots have been introduced in the patch to achieve wider bandwidth. Presented work provides a comparative result of the microstrip patch antenna with and without the slots. Fractional bandwidth of the basic antenna is 9% which is increased to 46% after introduction of the slots in the proposed patch antenna.
In the present work, an equation has been developed to calculate the side length of the equilateral triangular patch for given resonant frequency. With the previously existing equation poor accuracy has been achieved for the performance parameters of the triangular microstrip patch antenna. Modified formula enhances the accuracy of the performance parameters of the triangular microstrip patch antenna. Proposed formulae provide a nonlinear relationship between the resonating frequency and the dimensions of the equilateral triangular patch antenna i.e. the required performance parameters and the design parameters used in the simulation and fabrication process. With the help of calculated dimension, performance of triangular patch antenna has been analyzed for particular resonating frequency. Simulated results of proposed equation have been compared with the existing equation, and better accuracy in the results has been achieved with the improved formula. Proposed equation has been verified by simulating and fabricating various antennas, and measured results are found satisfactory.
