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

Modified microstrip-line-fed rectangular dielectric resonator ... A new modified microstrip-line-fed rectangular dielectric resonator antenna coupled with slotted ground plane for circular polarization, is proposed in this article. The circular polarization is achieved due to combination of modified microstrip-line-fed aperture slot on ground plane. Impedance Characteristics for Microstrip-fed Wide Slot ... various microstrip-fed wide slot antennas have been proposed, studies on the effect of the microstrip-fed offset and microstrip position are rare. In this paper, it is shown how the impedance characteristics of a microstrip-fed wide slot antenna structure depend on microstrip offset and microstrip position.
f arise due to the coupling between microstrip line and AEWS and open ended microstrip line, respectively. The impedance Z0 slot is the impedance due to AEWS that de-pends on its dimensions. The expression of each impedance Figure 2. Equivalent circuit of an antenna with microstrip line and wide-slot.

An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna Bandwidth Enhancement of a Microstrip Line-Fed Printed Bandwidth Enhancement of a Microstrip Line-Fed Printed Wide-Slot Antenna With a Parasitic Center Patch Abstract: A printed wide-slot antenna with a parasitic patch for bandwidth enhancement is proposed and experimentally investigated. A simple 50-Ω microstrip line is used to excite the slot. A rotated square slot resonator is considered as Microstrip-fed Vivaldi Slot | Antenna Magus Image of the Microstrip-fed Vivaldi slot antenna. When one compares the new Microstrip-fed Vivaldi with the staple feed Vivaldi which was included in Version 1.3, it has some notable practical advantages.. Tapered-slot antennas are often etched with other components onto the same dielectric substrate.
Circular polarization (CP) radiation of the shorted ring‐slot antennas is achieved by selecting a proper length of the shorted section in the ring slot, which is about 3.9 and 8% of the mean circumference of annular and square ring slots, respectively, and feeding the ring slot using a microstrip line 90° to the shorted section.

MICROSTRIP-FED SLOT ANTENNA ARRAY - ece.uci.edu A microstrip-fed slot antenna offers a better isolation between the feed and the material under measurement compared to the microstrip-fed microstrip antenna [3]. They are more flexible in integration with other active and passive devices in a hybrid MIC and MMIC design. Compact and Broadband Microstrip-Line-Fed Modified Rhombus ... The printed microstrip-line-fed broadband rhombus slot antenna is investigated in this paper. With the use of the offset microstrip feed line and the corner-trun-cated protruded ground plane, the bandwidth enhancement and the slot size reduction for the proposed slot antenna can be obtained. The experimental results demonstrate that the ... Study of coupled slot antennas fed by microstrip lines
