In this paper a novel design of a Slotted Rectangular Microstrip Patch Antenna with perturbation in ground plane is described which increases the interference rejection frequency bandwidth. A comparative study is also shown between two antenna with identical radiating element, one with a perturbed ground plane and another without perturbation. The proposed antenna is designed for operation at both...
In this paper a design approach of circular microstrip patch antenna for dual frequency response is proposed. The antenna dimensions are computed from the cavity model. Designs are made for dual-frequency responses at 2.04GHz and 2.9GHz. For better performance of the antenna coaxial probe feed technique is used for excitation. Two parallel slots and another orthogonal slot are introduced to a conventional...
This paper described the analysis and design of a square spiral Microstrip. The spiral is formed by introducing slot in a square patch. This spiral design is introduced to use a single structure for dual band/frequency operations by adding tuning elements. The antenna is modeled, designed and simulated using Ansoft HFSS software. The design parameters for a rectangular patch antenna have been calculated...
Microstrip antennas are excited for radiation modes using different techniques which lead to best impedance matching between the feed line and the patch. This paper describes two techniques which use microstrip line and also coaxial line as feed line for a rectangular patch. The analysis was carried out using ANSOFT High frequency structure simulator (HFSS). By changing the position of the feed point...
