In the azimuth plane, a hairpin filter loaded with meandering line is utilized as the phase-shifter. While in the elevation plane, an improved structure of the above filter with embedded varactors is implemented. In such a setup, phase progression along perpendicular directions are determined without interference, thus guarantee continuous scanning within a 2-D conical space.

This phase shifter is based on a 4th order lowpass filter constructed by a 50 Ω microstrip line and defected ground structures (DGSs). High-Q varactors are loaded on the etched DGSs on the ground to adjust cut-off frequency of the employed lowpass filter. Therefore, phase shift can be continuously tuned while cut-off frequency is changed. Equivalent circuit of a unit cell has been given to illustrate the mechanism of phase variation. The proposed phase shifter has been designed at L band and simulated using full-wave EM solver Ansys HFSS. Simulated results demonstrate a tunable phase shift of 98° at the operation frequency of 2 GHz when the bias voltage varies from 1 V to 10 V. This phase shifter shows a maximum insertion loss of 0.5 dB and return losses at both ports are more than 10 dB during the entire tuning process, which indicates good impedance matching.","PeriodicalId":163276,"journal":{"name":"2020 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123725139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed filter was made of three copper-coated SU-8 layers with the nominal thickness of 0.5 mm. The cylindrical resonators operate in TM010mode, hence the resonator frequency is independent with the height of the resonator and this reduced the difficulty to control the thickness of the SU8 layers. This filter is designed to have a center frequency of 90GHz, a fractional bandwidth of 5% and a passband return loss of 20dB. This paper also analyzes the dimensional sensitivity of the filter from two aspects: the thickness of the resonator and the assembly between the SU-8 layers. The sensitivity of bandpass response shows low sensitivity to this tolerance and S11is below -15dB. The frequency shift does not exceed 114.5MHz (0.127% of the center frequency).","PeriodicalId":163276,"journal":{"name":"2020 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117262577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
