This paper presents a simple, yet effective hands-on introduction to impedance matching in the frequency domain using the Digilent Analog Discovery Board. This experiment avoids the need for expensive RF/Microwave test equipment, by using basic low f

2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting.
An analysis of scanblindness onset angles in printed dipole arrays with perforated dielectric substrates is presented. The periodic grid of air holes in these arrays is shown to produce a photonic bandgap (PBG), which is identified as the root cause

The design, fabrication, and measurement of a 16 × 16 dual-polarized planar ultrawideband modular antenna (PUMA) array operating over 7-21 GHz (3:1 bandwidth) are presented. The array is comprised of tightly coupled dipoles printed on a grounded die

A fully planar ultrawideband phased array with wide scan and low cross-polarization performance is introduced. The array is based on Munk's implementation of the current sheet concept, but it employs a novel feeding scheme for the tightly coupled hor

A new wideband, wide-scan array is introduced, called the Banyan Tree Antenna (BTA) array, that employs modular, low-profile, low-cost elements fed directly from standard unbalanced RF interfaces. The elements consist of vertically-integrated, flared

Introduction Wideband, low-cost, and low-profile modular phased arrays are in high demand for future mutlifunctional systems. Currently, low-profile ultrawideband arrays such as the current sheet array (CSA) [1] or the fragmented aperture array (FSS)

A wideband phased array with an aperture made of two distinct element periodicities, which effectively thin the array, is presented. The topology is based on a “quantized” version of the wavelenght-scaled aperture of [1], and [2]. This thinning m
