An antenna array system is disclosed which uses subarrays of slots and subarrays of dipoles on separate planes. The slots and dipoles respectively are interleaved, which is to say there is minimal overlap between them. US5287116A - Array antenna generating circularly polarized… A microstrip antenna is disclosed which comprises a ground conductor plate and a patch opposed to the ground conductor plate with a particular distance, a transmission feed line and a reception feed line being disposed between the ground … Design An X-Band Vivaldi Antenna | Microwaves & Radio Frequency The microstrip lines widely used in microwave PCBs are unbalanced lines, although a Vivaldi antenna requires a feed with a slotline transmission line, which is balanced.

Antenna Research Papers - Academia.edu The tri-band antenna is obtained with etching a c-shaped slot on it, which has been used in a two elements MIMO structure. Microstrip Antennas Research Papers - Academia.edu View Microstrip Antennas Research Papers on Academia.edu for free. Radioengineering - September 2013, Volume 22, Number 3 With the use of the offset microstrip feed line and the corner-truncated protruded ground plane, the bandwidth enhancement and the slot size reduction for the proposed slot antenna can be obtained.
The most commonly employed microstrip antenna is a rectangular patch which looks like a truncated microstrip transmission line. It is approximately of one-half wavelength long. When air is used as the dielectric substrate, the length of the rectangular microstrip antenna is approximately one-half of a free-space wavelength.
A BROADBAND MICROSTRIP- TO-SLOT-LINE TRANSITION
The main structure is a slot-loaded microstrip patch antenna fed by a half-width microstrip line. Two different types of antenna structure are combinedRadiation from the antenna structure is achieved primarily from the first higher-order microstrip mode. The 10 dB return loss bandwidth of the antenna...
A Brief Tutorial on Microstrip Antennas (Part 1 ... The transmission-line model of the rectangular microstrip antenna utilizes an equivalent radiating slot of width W, and height h, to represent each of the radiating edges (Fig. 5). 5. Radiating slot equivalence to microstrip edges. MICROSTRIP-FED SLOT ANTENNA ARRAY - ece.uci.edu

Design, Analysis and Prototyping of a Microstrip-Fed Wide ... The antenna has two metal layers on either side of a single-layer PCB. The first metal layer is the microstrip feedline and the second layer of metal is the groundplane with a wide slot cut out from it. After defining the shapes, use Boolean subtraction to create the slot in the groundplane. Bandwidth Enhancement of a Microstrip Line-Fed Printed ... Abstract: A printed wide-slot antenna with a parasitic patch for bandwidth enhancement is proposed and experimentally investigated. A simple 50-Ω microstrip line is used to excite the slot. A rotated square slot resonator is considered as reference geometry. The rotated square slot antenna exhibits two resonances (f 1: lower resonant frequency, f 2: higher resonant frequency).
