Microstrip fed slot antenna array

An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna PIN SWITCHED MICROSTRIP SLOT ANTENNA ARRAY FOR 3D ... The design of 4×4 microstrip-fed slot antenna array has been presented in this paper along with its applicability in microwave image reconstruction of concrete structure defects. The measurement results show that the each microstrip slot antenna element in the array produces return loss good enough to be implemented in the microwave imaging.

Microstrip Antenna and Their Applications. Microstrip antenna are one of the most popular typesThese antennae are in the form of a slot or aperture in a metal plate and commonly used at higherIn an array antenna, several radiators separated from each other are geometrically arranged to give... Reconfigurable Microstrip Patch – Slot Antenna Array Index Terms—Antenna array, microstrip patch antenna, microstrip patch slot antenna, PIN diode.The frequency tuning characteristics of a slot antenna can be achieved by changing the slot effective length or by switching the connection between the feed and the ground. PIER Online - Circular Microstrip Slot Antenna for… By employing an offset microstrip-fed line and a strip close to the radiating edges in the circular slot patch, an antenna operating at dualThe second frequency is also tunable by varying the lengths of the microstrip-fed line.

EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA Key words: microstrip patch antenna, slots, bandwidth, gain, efficiency. 1.INTRODUCTION Microstrip slot antennas invented in 1938 by Alan Blumlein. Slot radiator or slot antennas are antenna that are used in frequency range from about 300 mhz to 25 ghz. They are often used in navigation radar usually as an array fed by a waveguide. Study and Design of a Differentially Fed Tapered Slot ... such antenna array concepts, thereby facing one of the biggest Abstract—The results of a parametric study and design of an ultra-wideband dual-polarized array of differentially fed Tapered Slot Antenna elements are presented. We examine arrays of bunny-ear antennas and discuss the capabilities and limitations of differential antenna technology. A Quad-Band CPW Fed Slot Antenna Array for LTE and WiMAX ...

antennas is becoming an important topic in microstrip antenna design. In this paper the design and development of a 2 × 1 array of a low cost slotted microstrip line fed shorted patch antenna (MFSPA) has been presented. Both the shorted patch and microstrip line feed network have air substrate. The material cost is thus reduced to a minimum.

Broadband Differentially Fed Tapered Slot Antenna Array… Traditional unbalanced tapered slot antennas often employ a bilateral strip line feed, or a separate feed board, in combination with a potentially lossy radial stub and microstrip lineTo overcome this drawback, a differentially fed tapered slot antenna array, which is conceptually based upon [4], has...
