The proposed antenna is composed of a microstrip circular patch radiator which is probe-fed by a PIN-diode-controlled switchable network on the other side of its ground plane to provide four different states of polarization. The feeding network is successively coupled to two additional microstrip resonators and the input microstrip line. Together with the resonant mode of the circular patch, a 3rd order equal-ripple filtering response is achieved. The measured fractional bandwidth of the proposed antenna is around 6.5% centered at 2.45 GHz. Measured in-band maximum antenna gain is 3.1 dBi. The proposed antenna has the advantages of multifunction, small dimension and simple structure for 2.4 GHz WLAN applications.","PeriodicalId":162908,"journal":{"name":"2019 IEEE Asia-Pacific Microwave Conference (APMC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129385216","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 stacked-FETs technique is a common method to increase the handling power. However, the conventional stacked-FETs structure has a critical issue that is the severe imbalanced voltage division across the FET stacks degrading the power handling capability and linearity in the presence of a large input power level. To further improve the power handling capability, we propose an enhanced switch biasing strategy to achieve even voltage distribution among the stacked FETs. Based on the new method, a stacked-FETs single-pole four-throw (SP4T) antenna switch in a 130nm silicon-on-insulator (SOI) CMOS process for high-power applications is devised as an experimental vehicle. The experimental results demonstrate that the proposed switch adopting the new biasing strategy reveals higher power handling capability and lower harmonic distortion compared to the conventional version, which is suitable for GSM-based and antenna tuning applications.","PeriodicalId":162908,"journal":{"name":"2019 IEEE Asia-Pacific Microwave Conference (APMC)","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132890358","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}

A 1 to 64 microstrip line power divider is proposed to feed the $8 times 8$ radiation patches. The radiation elements and the microstrip line feed network are on the same layer, so the antenna PCB only has two layers. By optimizing design the radiation patches and feed network, the antenna array shows good performance at W-band with the center frequency 94GHz.
