“…The multi-feed method can obtain better axial ratio characteristics, but the feed network is complex and large due to the application of multi-feed points. To notch up circular polarization through a single feed [8][9][10][11][12][13][14][15][16], it is necessary to feed in the orthogonal direction with a difference of 90 degrees to stimulate circular polarization. Due to the inductance effect on the surface of the patch, it is difficult to realize impedance matching and easy to produce machining errors.…”

A small ring antenna working at 2.45 GHz was designed in this paper, a small disk-coupled structure was applied to feed an inner-hole-biased ring patch, contributing to not only improving the impedance characteristics of the antenna but also reducing the size. The simulation results show that the designed patch area is only 70.7% of that of the traditional circular microstrip antenna on the premise of ensuring good bandwidth and gain performance; the −10 dB bandwidth of S 11 parameter is 62 MHz; the gain of the maximum direction is 7.11 dB; and the circular polarization of the antenna is also realized. This design has also been compared with several conventional designs. It is proved that the antenna has good comprehensive performance, and the antenna feed structure is simple, easy to process, very conducive to engineering applications. Finally, the feasibility of this technology was verified by contrasting the measured data with the simulation data.

“…To meet such features and requirements, the microstrip patch antenna have been proposed because of its low profile, less in cost, small in size. [1] Microstrip Patch Antenna consists of rectangular patch which is conductor in nature of length "L" and width "W" on one side of dielectric substrate with the thickness of "h" and dielectric constant "ε r " with the base named ground. Parameters like return losses, gain and VSWR are calculated in this paper.…”

This paper takes research on design of multiband microstrip patch antenna. The proposed patch antenna can resonate at seven unique frequencies between 2 GHz and 9GHz out of which four are considered to be useful bands. To accomplish multiband frequency, proposed finite element method is employed to design the rectangular Microstrip Patch Antenna (MPA). The circular patch is designed and then united with more circles to make a new design. The proposed antenna is designed on FR4 Epoxy substrate with specifications : relative permittivity = 4.4, relative permeability = 1, di-electric loss tangent =0.02 and thickness = 1.6 mm .The return loss for all the resonant frequencies is less than -10dB. The proposed design exhibits individual gain of 8.9 dB at 7.1 GHz where overall gain is 3.1 dB in the final iteration, and is used public sector applications i.e. military, business radio (police and fire) and in space science like radio astronomy. Frequency above 6 GHz are going to be used in future mobile communication in 5G.

The proposed design exhibits the overall gain of 9.5 dB On other hand, individual gain of antenna is 9.3 dB and 1.9 dB at 5.09 GHz and 9.36 GHz respectively in the final iteration, and is used for many satellite communications transmissions, some Wi-Fi devices, some cordless telephones as well as some surveillance and weather radar systems.
