[001]. The present invention relates to the technical field of
communication technology.
[002]. The present invention relates to the field of circular polarization
for a patch antenna embedded on a planar and fictional curved
structure with swastika slotted ground plane.
[003]. More particularly, the present invention is related to a planar
and fictional curve structured patch antenna with symmetrically
swastika slotted ground plane.
[004]. A circular polarized antenna throws its energy in each and
every plane through which EM wave propagates. The satellite
communication, mobile communication needs a circularly
polarized antenna, whose plane of polarization rotates 360 degrees
for each wavelength like a coin rotates on the plane. CP Patch
antennas are useful for short distance communication, portable
devices like Laptop etc. Flush-mounted patch antennas find
numerous uses in which they are placed on nonplanar structures
namely on the avionics and missile system because of its easy
placements in the curve structure. In between 1960's and 1970's,
interest in conformal antenna started to rise, but after that the
interest was decreased due to shortcomings of analytical tools.
[005]. Conformal micro strip antennas with singly feed are
compact in size. The ground plane requirements for doubly feed
antenna require more space as compared with first for the
production of 90-degree phase shift between two component of
transverse electric field ECD, Eel and two component of transverse
magnetic field H<D, HO, some perturbation on the structure of singly feed antenna is essential. In 1993, Kin-Lu Wong and Shyh
YeongKe investigated circular polarisation in cylindrical substrate
patch antenna.
[006]. Cylindrical patch antenna structure was first proposed by
Krowne . The cylindrical patch radiator using cavity model was
analysed and the variation of operating frequency had been shown
with the change of radius of cylinder. In 1989, K M Luk et.al
analysed and investigated the radiation pattern, input impedance
and quality factor using numerical method. A detailed analysis
cylindrical patch antenna using Galerkin methods for the solution
of integral equation was carried out by S M Ali in the same year.
[007]. In 1985, Joseph Ashkenazy et al defined the cylindrical antenna
and gave the theory in terms of surface currents where patch
radiators of the cylindrical patch antenna was replaced by current
distribution.
[008]. One standard literature on swastik slotted patch antenna is
investigated in. The designed antenna exhibits the result of triple
band based swastik slot embedded on the patch . Each band has
omnidirectional pattern at 2.44 GHz, 3.5 GHz and 5.98 GHz with gain of 3.97 dBi, 4.04 dBi and 3.25 dBi used for LAN and Wimax application [16].,
[009]. Some of the prior work is listed herewith:

07584197 Applicant MAYES PAUL E Inventor Mayes Paul E. A
planar antenna is described which employs a thin patch of
conductive material supported above and substantially parallel to a
closely spaced thin conductive ground surface. Two or more
narrow slots are positioned in the ground surface beneath the
conductive patch. A microstrip transmission line, placed below the
ground surface, excites the slots in series. The length of the
microstrip line between the slots, the position of the microstrip line
across the slots, and the dimensions of the slots are chosen to excite
two orthogonal modes in the conductive patch in phase quadrature.
This excitation results in a planar antenna which receives and
transmits electromagnetic waves of circular polarization. The
antenna may also employ a coplanar waveguide transmission line
instead of the aformentioned microstrip transmission line. The
coupling apertures then form slot discontinuities in series with the
coplanar transmission line, which are positioned under the
conductive patch. The antenna may also employ several conductive patches stacked over each other in a parallel fashion to enhance antenna performance.

[0027]. The present invention mainly cures and solves the technical
problems existing in the prior art. In response to these problems, the
present invention provides a planar and fictional curve structured
patch antenna with symmetrically swastika slotted ground plane.
[0028]. As one aspect of the present invention relates to a planar
and fictional curve structured patch antenna with symmetrically
swastika slotted ground plane, wherein the This is fictional antenna
as it is not possible to fabricate because the FR-4 substrate cannot be bent, The ground plane is made curved surface with a radius of curvature (ROC) of 7.96 mm which is calculated from the perimeter of cylinder (curved edge) equal to the one side of the ground plane of planar patch i.e. 50 mm, the height of the curved surface (i.e. straight edge) is equal to the other side of planar ground plane i.e. again 50 mm. The fictional curved ground plane is surrounded by FR- 4 substrate of thickness 1.6 mm above which
29.09 mm X 29.09 mm planar patch is bent.
[0029]. The principle objective of the present invention is to provide a
planar and fictional curve structured patch antenna with symmetrically
swastika slotted ground plane.
[0030]. Further clarify various aspects of some example embodiments of
the present invention, a more particular description of the invention
will be rendered by reference to specific embodiments thereof which
are illustrated in the appended drawings. It is appreciated that these
drawings depict only illustrated embodiments of the invention and are
therefore not to be considered limiting of its scope. The invention will
be described and explained with additional specificity and detail
through the use of the accompanying drawings.
[0031]. In order that the advantages of the present invention will be
easily understood, a detailed description of the invention is discussed
below in conjunction with the appended drawings, which, however,
should not be considered to limit the scope of the invention to the
accompanying drawings, in which:
[0032]. Figure 1 shows an exemplary representation of a planar and
fictional curve structured patch antenna with symmetrically swastika

[0035]. Although the present disclosure has been described with the
purpose of to a planar and fictional curve structured patch antenna
with symmetrically swastika slotted ground plane, it should be
appreciated that the same has been done merely to illustrate the
invention in an exemplary manner and to highlight any other purpose
or function for which explained structures or configurations could be
used and is covered within the scope of the present disclosure.
[0036]. The planar and fictional curve structured patch antenna
with symmetrically swastika slotted ground plane is disclosed
herewith.
[0037]. A planar and fictional curve structured patch antenna
with symmetrically swastika slotted ground plane, wherein the This
is fictional antenna as it is not possible to fabricate because the FR
4 substrate cannot be bent, The ground plane is made curved
surface with a radius of curvature (ROC) of 7.96 mm which is
calculated from the perimeter of cylinder (curved edge) equal to the
one side of the ground plane of planar patch i.e. 50 mm, the height
of the curved surface (i.e. straight edge) is equal to the other side of
planar ground plane i.e. again 50 mm. The fictional curved ground
plane is surrounded by FR- 4 substrate of thickness 1.6 mm above
which 29.09 mm X 29.09 mm planar patch is bent.
[0038]. A microstrip patch antenna, when given excitement with
either TM 01 or TM10 mode due to swastika slot at the ground, the
resonant frequency of the microstrip antenna will have good
agreement with RHCP of curved patch.
[0039]. The antenna has gain approximately 4.49 dBic at 2.25
GHz frequency with 3 dB axial beam width 127 degree and 178.21
degree in E plane and H plane respectively.
[0040]. Geometry of proposed single probe fed CP microstrip
antenna is shown in Fig. 1. Conduction current path lengths due to
swastika slots loading on the ground plane are responsible for the
production of circular polarization in the antenna [4]. Hence the
proposed ground plane is embedded by two symmetric swastika
slots along with one diagonal.
[0041]. Dimension of the proposed patch as follows:
[0042]. Length of the square patch (L): 29.09 mm X 29.09 mm;
[0043]. Ground plane dimension (S): 50 mm X 50 mm;
[0044]. Substrate: FR-4 (Thickness -1.6 mm & dielectric
constant 4.3);
[0045]. The location of feed along the axial direction fp = -9.89
mm from the centre along Y axis;
[0046]. Position of centre of swastika slots along the diagonal
[4]: 14.48 mm from the centre along the diagonal, the coordinate of
centre of swastika slots are (S/5,-S/5) and (-S/5, S/5) [4] where S is
the dimension of square ground plane;
[0047]. Dimension of wide slot of swastika (a)= 10.35 mm;
Dimension of narrow slot of swastika (b) = 2.71 mm (Fig 1);
[0048]. The input impedance of a simple patch antenna is
different from that one which is slot loaded. The change in
susceptance with frequency plays an important role for proper
impedance matching of antenna; hence impedance bandwidth
results with proper feeding at particular location in the patch..
[0049]. The figures and the foregoing description give examples of
embodiments. Those skilled in the art will appreciate that one or
more of the described elements may well be combined into a single
functional element. Alternatively, certain elements may be split into
multiple functional elements. Elements from one embodiment may
be added to another embodiment. For example, order of processes
described herein may be changed and are not limited to the manner
described herein. Moreover, the actions of any block diagram need
not be implemented in the order shown; nor do all of the acts need to
be necessarily performed. Also, those acts that are not dependent on
other acts may be performed in parallel with the other acts. The
scope of embodiments is by no means limited by these specific
examples.
[0050]. Although implementations of the invention have been described
in a language specific to structural features and/or methods, it is to
be understood that the appended claims are not necessarily limited to
the specific features or methods described. Rather, the specific
features and methods are disclosed as examples of implementations
of the invention.
