A compact rhombus-shaped slot antenna fed by microstrip ... In this paper, a novel design and experimental study of microstrip-line-fed rhombus-shaped slot antenna is presented. The proposed antenna shows an ultra-wide band (UWB) operation with good impedance matching by choosing appropriate rhombus-shaped slot and feeding structure. US8766855B2 - Microstrip-fed slot antenna - Google Patents A microstrip-fed antenna is disclosed having a first dielectric substrate and a second dielectric substrate. The second dielectric substrate is disposed on the first dielectric substrate and the first dielectric substrate has a relative permittivity greater than or equal to the second dielectric substrate. The antenna further includes a microstrip line formed in the second dielectric substrate ... Design, Analysis and Prototyping of a Microstrip-Fed Wide ... This example builds a model of a microstrip-fed printed wide slot antenna on FR4, analyzes it and finally enables prototyping by generating Gerber files. The design is intended for operation in the L-band and has a bandwidth of about 17% over the band 1.6 - 1.8 GHz. Microstrip-fed Vivaldi Slot | Antenna Magus

The transmission-line model represents the microstrip antenna by two slots, separated by a low-impedance .
antenna [2]. In, Microstrip patch antenna, the strip and slot combination offer an additional degree of freedom in the design of microstrip antennas. A microstrip ntenna a patch comprises a slot cut in the ground plane of the micro strip line such that the slot is perpendicular to the strip conductor of the microstrip line .The field of the
Microstrip-fed Vivaldi Slot | Antenna Magus The Microstrip-fed Vivaldi has some notable practical advantages over the staple feed Vivaldi. Tapered-slot antennas are often etched with other components onto the same dielectric substrate. The Microstrip-fed Vivaldi has the advantage that it can easily be integrated in the circuit. Design of Slot Antenna for Wideband Applications - ERNET The slot antennas can be fed by microstrip line, slot line and CPW. In this paper, we presented the design of slot antenna fed by microstrip line. The designed antenna has the frequency range from GHz. Slot antennas are popular omnidirectional microwave antennas. These antennas feature omnidirectional gain around the azimuth with horizon-tal Chapter 5 Impedance of Slot Antennas 5.1 Introduction present calculations for a slot fed by a microstrip line with a bolometer detector centered between the two slots. The feed line is electromagnetically coupled to the slot antennas so no direct connections to the ground plane are necessary which simplifies the fabrication of the feed network and antennas. We present calculations HFSS - Design of Rectangular Patch Antenna using
The wider the strip is, the lower the characteristic impedance (Z0) is for that section of line. Coaxial Cable or Probe Feed. Microstrip antennas can also be fed from underneath via a probe as shown in Figure 3. The outer conductor of the coaxial cable is connected to the ground plane, and the center conductor is extended up to the patch antenna.
