Microstrip patch antenna. The design and simulation of patch antennas is widely used in mobile cellular phones today, and our emphasis in this work is on optimization of a 2.4 GHz rectangular Microstrip patch antenna. The return loss and the various gain plots have been studied along with the radiation patterns. Slot Antenna Uses Dual Polarization | Microwaves & Radio ... The antenna radiates in a broadside direction and features almost symmetrical radiation patterns in both the E- and H-plane directions. As Fig. 4 shows, the antenna’s cross-polarization remains under -35 Db; the front-to-back ratio is less than 18 dB; and the half-power beamwidth is about 108 deg. in the E-plane and 92 deg. in the H-plane.

Effect of Slot Rotation on Rectangular Slot based Microstrip ... 5 shows the VSWR values for different slot angles. Fig.4 Radiation patterns for different slot angles From these results, we estimate that the as-designed microstrip patch antenna may work successfully for different frequency applications. The radiation pattern is also changing with respect to rotational angle of a slot. Design Of A Wideband Dual-polarized Cavity Backed Slot Antenna A new technique for designing wideband dual-polarized cavity-backed slot antennas is presented. The structure is in the form of a double-resonant, dual-polarized slot antenna backed by a shallow substrate integrated cavity with a depth of approximately λ 0/10, where λ 0 is the wavelength in free space. The presence of the A cavity-backed coplanar waveguide slot antenna array A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. Microstrip Patch Antennas - EM Lab
Maximizing Gain of a Compact UWB Tapered Slot Antenna
Abstract— In this study, a 28-GHz U-slot rectangular microstrip patch antenna for 5G Applications is proposed. The U-slot antenna concept has been used in patch antenna designed to reduce antenna size.The U-slot patch antenna structure consists of a patch, U-shaped slot, a ground plane and coaxial feed lines. Slot Loaded Square Microstrip Patch Antenna for Dual Band ... With the help of slots near the radiating edges of the patch, the typical microstrip patch antenna can be twisted for. multi-frequency operation. The proposed antenna provides. dual-frequency operation by dint of three rectangular slots. close and par allel to the patch radiating edges.

Slot Antenna Uses Dual Polarization. The antenna, excited by two coaxial-line feeds, is composed of four T-shaped slots and four cross-shaped slots in the radial directions of a circular patch. Eight upright parasitical rods are placed around the antenna to realize a broad beamwidth radiation pattern.
