Low thermal drift, tunable frequency voltage controlled oscillator
TL;DR: An oscillator comprising a cascode configured device having first, second and third terminals, a plurality of resonators and first circuitry coupled between the plurality of resonance and the second terminal of the cascode configurable device is considered in this paper, where the first circuitry is operable as an evanescent mode buffer to compensate for changes in the capacitance of the oscillator during operation.
Patent
Wideband voltage controlled oscillator employing evanescent mode coupled-resonators
TL;DR: In this article, a voltage controlled oscillator comprising an active device having a plurality of resonators coupled across two terminals of the device and at least one resonator coupled across the plurality of the resonators is described.
Patent
Low noise, hybrid tuned wideband voltage controlled oscillator
TL;DR: An oscillator comprising an active device having first, second and third terminals, a plurality of micro-stripline resonators coupled together to form a coupled-resonator network, the coupled resonator network being coupled to the second terminal of the active device and a tuning network coupled to a coupled resonance network, with the tuning network being operable to adjust the coupling between at least two of the resonators as mentioned in this paper.

A compact circularly polarized rotated l-shaped antenna with j-shaped defected ground strucutre for wlan and v2x applications
TL;DR: In this article , a microstrip-line fed printed antenna for wideband circular polarization (CP) radiation is proposed, which utilizes a crescent-shaped substrate, rotated L-shaped monopole, and defected ground structure (DGS) to achieve a wide 3-dB axial ratio (AR) bandwidth and 10-dB impedance bandwidth (ZBW) across the entire 5GHz Wireless Local Area Network (WLAN) and Vehicle to Everything (V2X) operational bands.
