The antenna structure includes a two layer corporate feed network, which is partially embedded, connected with vias, otherwise known as ‘stitched’. First, using 4×4 microstrip patch arrays as the unit array, a 6.5° beam steer is observed when a 90° phase difference is applied to a 4×8 antenna array. The stitched 4×8 antenna array has a 3 dB beamwidth of 12° and a maximum gain of 15.4 dB with no phase shift, and the gain drops to 13 dB with a phase shift. Next, a 16×16 antenna has been constructed applying the stitching concept.

Some topics have proved of durable importance, others have faded in significance over the years while new topics continually emerge.

The filter is a four-pole cavity resonator band-pass filter. It is fabricated in silicon using the KOH-wet etching technique, and the filter is assembled by bonding two silicon wafers. The proposed configuration enables the realisation of low-loss and low-cost filters, which are easily integrable, monolithically or in a hybrid fashion, in microwave front-ends. Further, as it is described in the paper, the arrangement proposed for the cavity resonators allows for the realisation of cross-couplings between the cavity resonators, and it makes possible the design of compact linear phase filters. This paper presents the design and the measurement of a single micro-machined cavity resonator, and it describes the design procedure of the four-pole filter. This design of the complete four-pole micro-machined linear phase filter is finally assessed by full-wave simulation.","PeriodicalId":232128,"journal":{"name":"2009 European Microwave Conference (EuMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130977432","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 lumped coupling elements between two ports make it possible for the filter to generate three transmission Zps, and the position of the zero in the upper stopband is controllable by adjusting the capacitance value and the position of interdigital capacitor. At the same time, the centre frequency and bandwidth are both not changed. Then, the bandwidth of filter can be just adjusted by the different length of short-circuited branch. A compact filter operating at 3 GHz with a fractional bandwidth of 26% and minimal insertion loss of 0.7 dB and three Zps has been designed and fabricated.
