U-slot stacked patch antenna using high and low dielectric constant material combinations in S-band

Numerical Analysis of Slot Position of Rectangular U Slot Microstrip Patch Antenna

“…Both experimental and theoretical results of the antenna had been verified [10]. The physical parameters for example length of U slot, width of U slot, height and size of patch, probe location, substrate permittivity can greatly affect the antenna's performance [6]. In this paper the effect of various values of slot length and slot width on return loss and gain has been analyzed.…”

“…Another technique includes the use of the parasitic elements lying on same layer or another layer (stacked). The aperture coupled excitations also used to achieve the wider bandwidth but this method is having a complication of fabrication process [6].…”

Improvement in Radiation Parameters Using Single Slot Circular Microstrip Patch Antenna

“…Coaxial probe fed microstrip antennas provide excellent isolation between the feed network and the radiating elements and yield very good front to back ratios [5]. Among the conventional microstrip antenna geometries, circular microstrip antenna is most widely analyzed antenna due to easy modeling and applicable boundary conditions [6]. The major drawback of circular microstrip patch antenna is narrow bandwidth and low gain especially at lower microwave frequencies [7].…”

Bandwidth Improvement Using Slotted Triangular MPA

“…MPA have the advantage of low cost, thin profile, light weight, ease of fabrication, conformable to mounting surface and being integrated in active devices [1]. Also Coaxial probe fed microstrip antennas provide excellent isolation between the feed network and the radiating elements and yield very good front to back ratios [1].…”

“…Also Coaxial probe fed microstrip antennas provide excellent isolation between the feed network and the radiating elements and yield very good front to back ratios [1]. Due to this many advantages, MPAs have many applications like space technology, aircrafts, missiles, tracking, mobile communication, GPS systems, remote sensing and satellite broadcast [2] [3].…”
