An impedance-matching technique for increasing the bandwidth of microstrip antennas
Hugo Pues,A. Van de Capelle +1 more
TL;DR: In this article, the authors proposed broadband impedance matching as a natural way to increase the bandwidth of conventional microstrip patch antennas and found that by using an optimally designed impedance-matching network, the bandwidth can be increased by a factor of at least 3.9, the exact value depending on the degree of matching required.
Journal ArticleDOI
Microstrip stepped impedance resonator bandpass filter with an extended optimal rejection bandwidth
Jen-Tsai Kuo,E. Shih +1 more
TL;DR: In this paper, the fundamental and higher order harmonics of an SIR were analyzed against the length ratio of the high-Z and low-Z segments to obtain an optimal length ratio for each high-z to low-z impedance ratio to maximize the upper rejection bandwidth.
Journal ArticleDOI
Synthesis of cross-coupled resonator filters using an analytical gradient-based optimization technique
TL;DR: In this paper, a general approach to the synthesis of cross-coupled resonator filters using an analytical gradient-based optimization technique is proposed, where the gradient of the cost function with respect to changes in the coupling elements between the resonators is determined analytically.
Journal ArticleDOI
A varactor-tuned RF filter
A.R. Brown,Gabriel M. Rebeiz +1 more
TL;DR: In this paper, an electronically tunable filter at 1 GHz was presented, which has a 60% tuning range from 700 MHz to 1.33 GHz with a low insertion loss.

Acoustic surface wave filters
R.H. Tancrell,M.G. Holland +1 more
TL;DR: In this article, the authors developed models to describe delay lines and compared the predictions of these theories with several experimental filters, including band-pass filters and dispersive delay lines, in the UHF range, and the frequency response is determined by the finger spacing and overlap of the interdigital comb structures used as input and output transducers.
