DESIGN OF E-SHAPE RECONFIGURBLE MICROSTRIP ANTENNA FOR ULTRA WIDE BAND APPLICATIONS

Journal of Engineering and Sustainable Development, 2018
In this paper, a frequency and radiation reconfigurable microstrip antenna design is proposed for Ultra Wide Band application (UWB). The radiating patch was an E-shaped microstrip printed over an FR-4 substrate with a relative dielectric constant of 4.3,

Superstrate-integrated Switchable Beam Rectangular Microstrip Antenna for Gain Enhancement [PDF]

Radioengineering, 2017
This research has proposed a switchable beam rectangular microstrip antenna with double parasitic patches, in which two PIN diodes were deployed for manipulation of the main beam direction and a superstrate (i.e. either a dielectric slab or metamaterial)

Small Microstrip Patch Antennas

Electronics Letters, 1995
As stated in Chapter 1, one of the many advantages of microstrip patch technology over its competitors is its low profile and hence small volume. Another key advantage of this printed antenna is the relative ease in which it can be connected to the feed network, as was highlighted in Chapter 2.

Development of Low-Loss Bandpass Filters With Multiple Controllable Transmission Zeros by Using an Improved Connecting-Line Coupling Technique

IEEE Access
This paper presents a novel connecting-line coupling technique for the design of compact and low-loss bandpass filters (BPFs) with multiple controllable transmission zeros (TZs). Traditional gap-coupling methods are highly sensitive to fabrication errors

Relationship between electromagnetic characteristics of transitions and different interconnect angles in microwave communication circuits

Tongxin xuebao, 2014
Transmission lines connected to the two ends of via in coplanar waveguide (CPW) to CPW transition and/or CPW to microstrip (MS) transition are not always in line,but in arbitrary angle.The propagation characteristics of these structures are simulated and
