Microstrip patch antenna arrays are used in a number of industries as transceivers of radar and RF signals. This is a prime candidate for the 5G mobile network system. The app simulates a single slot-coupled microstrip patch antenna, fabricated on a multilayered low-temperature cofired ceramic (LTCC) substrate. Feb 01, 2001 Jan 01, 2016 Design of an 8X1 Square Microstrip Patch Antenna Array 75 The dimensions are w = 7.6 cm, h = 3.175mm, ε r = 2.2 and a = 9.5 cm. When the inter-element distance is selected to be 0.73 λ, the 8X1 array satisfies 90 beam width. Jun 12, 2012

Jan 01, 2016 · 4. Conclusions Antenna array concept is used to improve the better gain of different antennas by nullify the side lobes. This paper explains about a 3x3 Rectangular microstrip patch antenna Arrays using HFSS 14.0. For the proposed design this paper got a high gain of 17.29 db, return loss at 13.33 hz and the VSWR value is 0.7807 (value<2).

The antennas are designed for the wireless application operating in the frequency range of 3.3 GHz to 3.6 GHz, and UK based fixed satellite service application (3 GHz to 4 GHz), and are named as single inverted patch conventional rectangular microstrip antenna (SIP-CRMSA) and slots embedded inverted patch rectangular microstrip antenna (SEIP-RMSA), respectively. The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.

Lohokare [22] highlighted Microstrip Patch Antenna Loaded with Magnetoinductive Waveguide . Chen and Zhang [23] 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 [25] is designd by Song and Zhang. antennas such as microstrip and printed slot antennas are required. Printed slot antennas fed by a coplanar waveguide (CPW) have several advantages over microstrip patch antennas. Slot antennas exhibit wider bandwidth, lower dispersion, and lower radiation loss than microstrip antennas, and when fed by a coplanar Slot antennas in waveguides provide an economical way of the design of antenna arrays. The position, shape and orientation of the slots will determine how (or if) they radiate. Figure 3 shows a rectangular waveguide with a drawn with red lines snapshot of the schematic current distribution in the waveguide walls. Jun 16, 2015 · In this letter, a microstrip-fed dual-polarized stepped-impedance (SI) slot antenna element with a low profile is first proposed. The antenna is composed of two pairs of SI slots excited by two orthogonal stepped microstrip feedlines. The broadband characteristic is achieved by combining the fundamental and spurious resonances of the SI slot resonators, while the good cross polarization is A novel high gain slot dipole antenna array fed by a coplanar waveguide (CPW) for 5GHz band wireless local area network (WLAN) application is proposed. Antenna element of our proposed antenna array is one sided directional slot antenna with bottom floating metal layer. This antenna array has 16 antenna elements to achieve a high gain. The RF signal is injected by CPW transmission line. The

Radar. The antenna consists of an array of SIW slot elements, a CPW-SIW transition and a CPW power divider. A new type of CPW-SIW transition is proposed to minimize the blockage aperture of the slot antenna array for suppressing the sidelobe levels advantages of microstrip antennas because they can be of the array.

The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.

Benefits or advantages of Microstrip Antenna Following are the benefits or advantages of Microstrip Antenna : They operate at microwave frequencies where traditional antennas are not feasible to be designed.

A Microstrip patch antenna is a narrowband, wide- beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating substrate.

Microstrip antennas suffer an inherent disadvantage of narrow impedance bandwidth, normally within 5%. In this article, a single layer linear U-slot microstrip
