This paper presents an analysis for the resonant frequencies and its various harmonics of a nearly Circular Annular Ring Microstrip Antenna (ARMSA) with and without air gaps and superstrate loadings. This ARMSA is studied for various radii of the inner and outer radiating circular edges of disc. Three such nearly circular ARMSA are analyzed with an Aspect(More)
This paper presents the effect on circular polarization of multilayer circular annular ring patch (CARP). A CARP have been fabricated on FR4 substrate of dielectric constant 4.2 and thickness 1.52mm. Experimental resonant frequency impedance bandwidth and Axial ratio of simple CARP, covered CARP, spaced dielectric CARP and CARP with two superstrates have(More)
This paper presents the effect on resonant frequency of multilayer circular annular ring microstrip antenna. Three nearly circular annular ring microstrip antennas (ARMSA) have been fabricated on FR4 substrate of dielectric constant 4.3 and thickness 1.53mm of various dimensions. Experimental resonant frequency of simple circular ARMSA, covered circular(More)
This paper presents an optically transparent circular shaped microstrip patch antenna. The transparent circular microstrip antenna comprises a thin sheet of soda lime glass substrate with conductive ITO film coating for radiating patch and ground plane and is feed through a CPW feeding technique. The circular shaped patch is modified by inserting inset(More)
This paper, presents a single band Microstrip Patch Antenna for WiMax application. The planner geometry of designed antenna consists of ground, substrate, patch, feed and slot. The designed antenna has been optimized using CST Microwave studio software for 3. 41-3. 64 GHz band with corresponding bandwidth of 223 MHz. The gain of 3. 8 dBi and directivity of(More)
This paper presents planar modified circular slot antenna with asymmetric Y-shaped feeding technique. The CPW asymmetric Y-shaped feeding structure is electromagnetically coupled to the modified circular shaped radiating patch. The proposed antenna is made circularly polarized by innovative Y-shaped asymmetric arm feeding structure. The antenna covers the(More)
