A novel single feed compact microstrip patch antenna with slits and symmetric-fractal boundary loading is proposed and investigated for circularly polarized (CP) radiation. The compact size of the antenna is realized by insetting four pairs of equally spaced slits of equal lengths to the boundary of square patch along the patch axis. Further size reduction and CP operation is achieved by symmetrically...
In this communication, a practically realisable artificial planar magneto-dielectric (MD) meta-substrate is proposed and investigated for microstrip patch antenna miniaturisation. The meta-substrate employs cross-coupled twisted metallic split-ring resonator ring pairs to achieve effective permeability (μeff) and permittivity (ɛeff) greater than that of the host dielectric which leads to antenna miniaturisation...
A novel fractal microstrip patch antenna has been proposed which is based on the Smith Chart design. The Smith Chart circles consist of two types of circles. The proposed design of fractal microstrip patch antenna has exploited one set of Smith Chart circles. The dielectric material used for the proposed microstrip patch antenna is Rogers TMM4 with a dielectric constant of 4.55 and the patch is made...
The Fractal geometries have unique properties such as space filling and self similarity. For achieving the desired miniaturization, multi-band and wideband properties the fractal geometries have been exploited in antenna designing. The paper proposes a novel geometry called as modified Sierpinski fractal for better performance as compared to the traditional existing Sierpinski geometry. The proposed...
A novel bow-tie slotted substrate integrated waveguide (SIW), leaky wave antenna is proposed and investigated. This antenna works in the TE10 mode. Proposed antenna leads to more intense electric field and better coupling of E-field in adjacent slots, which results in more uniform spectral behavior in comparison with transverse slot leaky wave antenna. In addition to this proposed antenna gives improved...
In the present paper, a wideband circularly polarized microstrip antenna is designed for application in wireless local area network(WLAN). The proposed antenna is L-strip fed proximity coupled circular microstrip antenna where the radiating patch is loaded by a cross slot of unequal arms length. The circular polarization is achieved by cutting an asymmetric slot cut on circular radiating patch to...
The main objective of this paper is to design and optimize the edge fed microstrip patch antenna and to improve efficiency by improving the parameters such as return loss and frequency of operation. In this paper, the various antenna characteristics for patch antenna are achieved by using dege feeding techniques. The patch antenna using edge feed is simulated using IE3D simulator for 3.3GHz operating...
