The dielectric loading of a microstrip antenna affects both its radiation pattern and impedance bandwidth.These slots act as an array and have the highest directivity when the antenna has an air dielectric and decreases as the antenna is loaded by material with increasing relative dielectric...
gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency. Key words: microstrip patch antenna, slots, bandwidth, gain, efficiency. 1.INTRODUCTION Microstrip slot antennas invented in 1938 by Alan Blumlein. Slot Loaded Circular Microstrip Antenna with Meandered Slits Slot loaded microstrip antenna with slits 1853 basic circular patch antenna can be approximately calculated as  fr = knm c 2R e r (1) in which knm = m th zero of the derivative of Bessel function of order n , c = velocity of light, R e = ee ctive radius of the circular disk r … Analysis of W-slot loaded patch antenna for dualband The geometry of W-slot loaded patch antenna which is coaxially fed is shown in Fig. 1.The analysis of the proposed antenna is carried out by considering two slots that are parallel (α = 0 0) to the radiating edges of the patch (L Sp × W Sp) and another two slots that are at an angle α = 30 0 having dimension (L Si × W Si) ().Download full-size image
Microstrip patch antenna (MPA) is widely implemented in different communication systems. One of the main disadvantages of MPA which limits its applications is its narrow bandwidth. In this paper I enhanced the bandwidth of MPA by inserting multiple slots in its ground plane.

Slot loaded microstrip antenna with slits 1853 basic circular patch antenna can be approximately calculated as  fr = knm c 2R e r (1) in which knm = m th zero of the derivative of Bessel function of order n , c = velocity of light, R e = ee ctive radius of the circular disk r = dielectric constant of the substrate. Slot-Loaded Microstrip Patch Sensor Antenna for High ... A slot-loaded microstrip patch sensor antenna is proposed to enhance sensitivity in measuring the permittivity of planar materials. A thin rectangular slot was etched along the radiating edge of a rectangular patch antenna fed by a microstrip transmission line. Two resonant frequencies were created at a lower frequency compared to the single resonant frequency of a conventional ordinary patch ...
slot-loaded microstrip patch antenna fed by coaxial probe. A coaxial feed, notched rectangular-slot loaded, microstrip antenna is proposed for linear polarization. The compactness of the antenna is easily obtained by inserting a square-slot. The square-slot-loaded microstrip antenna is simulated using IE3D software.

Lohokare  highlighted Microstrip Patch Antenna Loaded with Magnetoinductive Waveguide . Chen and Zhang  described Bandwidth enhancement of a microstrip-linefed printed wide-slot antenna with a fractal shaped slot. A novel monopole antenna with a self-similar slot for wideband applications  is designd by Song and Zhang. Microstrip antenna - Wikipedia The half-wave rectangular microstrip antenna has a virtual shorting plane along its center. This may be replaced with a physical shorting plane to create a quarter-wavelength microstrip antenna. This is sometimes called a half-patch. The antenna only has a single radiation edge (equivalent slot) which lowers the directivity/gain of the antenna. Comparative study of slot loaded rectangular and ... - Issuu Abstract In this paper we have presented the comparative study and theoretical validation of two element slot loaded rectangular microstrip array antenna (TS-RMAA) and two element slot loaded ... EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA antenna. In this paper we have seen the effect of slot on microstrip patch antenna. By the use of slot we can enhance bandwidth, gain e.t.c.. Return loss is reduce. Axial ratio and radiation pattern is also improved. By the use of slot microstrip antenna can be used in many application.
