Planar dual-band microstrip antenna
TL;DR: In this paper, a dual-band microstrip antenna is introduced, which consists of multiple layers with metallic strips placed at one of the dielectric interfaces under the radiating patch.

Tunable patch antenna using a liquid crystal substrate
Ranjan Bose,Aloka Sinha +1 more
TL;DR: In this article, the authors proposed the use of a liquid crystal substrate for a patch antenna whose frequency can be tuned by changing the biasing voltage across the substrate, which can be found by simulations that by varying the voltage from 0 V through 11 V, the operating frequency of the circular patch antenna can be varied from 1.08 GHz through 2.35 GHz.

Multi-layer dual-band microstrip antenna
TL;DR: In this article, a new dual-band microstrip antenna is introduced, which consists of multiple layers and is planar without any structure perpendicular to the ground plane, and the antenna is easy to fabricate.
The Design of Dual or Multi-Band Microstrip Antennas by Using Disturbing Patches
TL;DR: In this article, the authors employed various shapes and numbers of disturbing patches in microstripcavity to design for dual or multiple-band operation, and they showed that even only one disturbing patch can produce two different modes, and the radiation is still within an acceptable range.
Patch antennas on inhomogeneous substrates
TL;DR: Rylander et al. as mentioned in this paper analyzed patch antennas on inhomogeneous substrates with the stable FEM-FDTD hybrid method and an analytic propagator technique and found that a decrease of the permittivity in the vicinity of the patch increases the bandwidth and the resonance frequency.

A dual-frequency stacked circular-disc antenna
Stuart A. Long,M. Walton +1 more
TL;DR: In this paper, the dual-frequency behavior of a pair of stacked circular-disc printed-circuit antennas is investigated experimentally and the input impedance is measured as a function of the sizes of the discs with emphasis placed on the values of the two resultant resonant frequencies.
Journal ArticleDOI
Analysis of Microstrip Resonators
TL;DR: In this article, an accurate and efficient method was developed for computing the resonant frequencies of microstrip resonators, which was carried out rigorously using the full-wave analysis rather than the quasi-static approximation.
Journal ArticleDOI
Microstrip antennas for dual-frequency operation
TL;DR: In this paper, a hybrid multiport theory is developed for a single element microstrip antenna for dual-frequency operation and theoretical results are found to be in excellent agreement with the measured.

Equivalent Reactance of a Shorting Septum in a Fin-Line: Theory and Experiment
TL;DR: In this article, the results of theoretical and experimental investigations of the equivalent reactance of a shorting septum in a fin-line are presented and compared for several different fin-lines.

Dual-band microstrip antenna with an airgap
Chanam Lee,V. Nalbandian +1 more
TL;DR: In this article, a dual-band microstrip antenna is demonstrated, where the resonant frequencies can be varied over a wide frequency range and the input impedances are easily matched for both resonance frequencies.
