## Abstract This article presents an electronically tunable varactor‐loaded microstrip bandpass filter based on the planar split ring resonators (SRRs). The varactor is a reverse‐biased semiconductor diode, and is connected between the concentric rings of the SRR. An individual varactor loaded SRR

✦ Synopsis
The experimental results for a high-Q tunable MMIC bandpass filter designed and reported earlier are presented. Experimental results demonstrate a 16% tuning bandwidth, with the filter offering unloaded Q-factors more than 1200 o¨er a 1 GHz tuning range. ᮊ 1999

## Abstract A novel microstrip bandpass filter using a dual‐mode square‐ring resonator is presented in this paper, in which the input/output microstrip lines are arranged under the square‐ring to improve the coupling between the microstrip lines and the square‐ring. The filter has been investigated
## Abstract A novel dual‐mode bandpass filter using a microstrip triangular ring resonator with coupling stubs has been designed and tested. The basic configuration of this novel dual‐mode filter is a triangular ring resonator. Quasi‐L‐shaped I/O arms used as coupling stubs for enhanced coupling ar
## Abstract A C‐band bandpass filter is designed using modified ring dielectric resonator in microwave integrated circuit (MIC) environment for improved spurious response. The dielectric resonator (DR) filters are generally made in cavity environment because of its good spurious response in cavity
A novel, planar inverted-F antenna with a slotted T-shaped ground plane is proposed. It is shown that introducing a cross-shaped slot onto the T-shaped ground can greatly broaden the bandwidth without affecting the operating frequency. The measured bandwidth of the proposed antenna is from 1950 to 2
## Abstract An ultra wideband bandpass filter with sharp‐rejection is proposed by using a new structure of double ring resonators. The double ring resonator generates a couple of attenuation poles, and its operation mechanism is made clear through the even‐ and odd‐mode analysis of the circuit. The
