The antenna is made up of a trapezoidal-shaped monopole radiator, which was inspired by a rectangular monopole antenna. The ground plane is modified by embedding T and L-shaped slots to notch the desired operating frequency. The proposed antenna can switch to six different frequencies using RF PIN diodes, making it suitable for modern wireless applications. A multilayer frequency selective surface (FSS) reflector is presented to improve the gain of the proposed reconfigurable antenna. The low-profile design achieved a significant increase in gain while retaining the UWB antenna's excellent impedance bandwidth. Because of the use of the FSS reflector, the antenna's average peak gain has increased from 6 to 10.4 dBi. The proposed antenna has a wide switching capability, which validates its unique feasibility for high-speed multipl...

The proposed antenna has been designed for S-band application (2483.50- 2500.00 MHz) with 16.5 MHz bandwidth for IRNSS receiver application. CMA technique has been used to determine the optimum feed location on antenna to obtain circular polarization (CP) for excitation of two orthogonal modes (TM10 and TM01) with equal in amplitude and 90º out of phase. The proposed antenna uses probe feed configuration and design using dielectric laminates FR4 (dielectric constant is 4.3 and loss tangent is 0.025). The axial ratio bandwidth (< 3 dB) of the proposed antenna is obtained from (2431.4 to 2562 MHz). The aim of this antenna to improve the technology of designing of antenna so as small in size miniaturization, less complex, better-improved parameters, rejection and easy to designing and integration with...

Four different geometry has been chosen for this. In that, 2 similar slots have been etched diagonally on the square microstrip patch. Four slots like square, circular, ring and cross-shaped was selected in order to create and prove circular polarization behavior. Axial ratio (A.R.) performance plot reflects the required circular polarization characteristics. Antennas performance was characterized with respect to reflection coefficient, impedance plot and three dimensional patterns. One of the antennas was fabricated in the laboratory and experimentally measured in order to validate the procedure.

In order to design, a simplest geometry of the patch antenna is chosen. Antennas of different length, width and feed locations are simulated. Antennas have been analyzed with various performance parameters such as impedance, radiation pattern, reflection coefficient, directivity and VSWR obtained. In order to validate the design approach, MATLAB simulation results for four antennas have been compared with the results obtained from electromagnetic CST simulator. Also one of the antennas has been fabricated in the laboratory and experimentally measured.

The impedance bandwidth of the proposed antenna is 13.4 GHz (1.8–15.2 GHz). To enhance the gain of the antenna, a FSS reflector is employed below the suggested ultra wide-band antenna. A novel FSS, which consists of 5 × 5 array of elements, located at a distance of 1.01 λ (36.14 mm) below the proposed antenna. There is 4–5 dBi improvement in antenna gain after application of the FSS. In order to observe the signal correlation of the proposed antenna, the time domain analysis using similar antennas in face-to-face and side-to-side scenarios has been performed using the EM simulation tool CST-STUDIO. The simulated results of the proposed antenna exhibit good agreement with the experimental results of the prototy...
