“…This antenna may be a useful alternative to the heavy waveguide structures as EMI sensors. Though the major limitation with such an approach is the narrow band performance of this antenna, this study may be extended for other microstrip antennas with broadband characteristics [16][17][18][19].…”

Abstract-This paper presents the result for antenna factor of microstrip patch antenna when used as electromagnetic interference (EMI) sensor. Antenna factor is an important parameter of a sensor used for EMI measurements. The microstrip antenna has found wide application as transmit and receive antenna in modern microwave systems. In this paper, a new application of microstrip antenna as EMI sensor is presented. The result for antenna factor versus frequency of a microstrip patch antenna is presented using commercial software CST Microwave Studio. Also the experimental results for a prototype antenna are presented and compared with the simulated result.

Abstract-A new multi-layer planar array architecture to achieve multi-polarized radiation is developed in this paper. The design concept is based on embedding U-shaped coupling slots in the ground plane to extend the bandwidth. The proposed antennas have two feed ports, by adjusting the feeding properly, the antennas can transmit arbitrary elliptic polarized signal theoretically. Return loss and radiation patterns are measured for the 1-element, 2-element, 4-element, 16-element antenna arrays at 12.5 GHz. Radiation patterns of the antenna arrays show close agreement to the predicted ones in the shape of the main beam. By further incorporating properly designed feed networks, the −20 dB return-loss bandwidth of the proposed antenna arrays can cover the 12.5 GHz frequency band .Design details and experimental results are presented and discussed.

“…The high dielectric permittivity will also maintain the compactness of the structure whereas low dielectric permittivity will provide more efficient result. Bandwidth of the microstrip patch antenna can also be increased by increasing the thickness of the substrate material [6,7]. The major disadvantage of increasing thickness is the reduced efficiency since the large portion of the input power is dissipated in the resistor which takes away the available power that can be radiated by antenna.…”

Abstract-In this paper, we have simulated a single-pin-shorted microstrip line fed three-dielectric-layer (with different permittivity and thickness) rectangular patch microstrip antenna for all those communication systems whose limited antenna size is premium. Low permittivity hard foam has been used as one substrate to achieve wide bandwidth. The simulation of this proposed antenna has been performed by using CST Microwave Studio, which is a commercially available electromagnetic simulator based on the finite difference time domain technique.
