In this research, the presented antenna is developed from a driven element with coaxial probe, while four parasitic elements surrounded the driven element with shorting pin integration embedded inside the substrate which represent by a copper strip material. The four parasitic elements act either as reflector or director depending on the shorting pin configuration as reflect to Yagi-Uda patch antenna concept. By adjusting the status of shorting pin location either ON or OFF mode simultaneously on the parasitic elements, the radiation pattern can be varied, thus achieving the radiation configurability. This shorting pin contribute to the antenna’s electrical dimensional changes that manage to control the beam steering and return loss performance. By managing the ON and OFF state condition of the integrated shorting pin, nine beam steering angles can be achieved. The proposed Multiple-Input Multiple-Output (MIMO) antenna consists of two identical patch elements with certain D separation distance on the Rogers RT5880. The significant parameters performance such as mutual coupling and correlation coefficient are been observed. Both antenna designed and simulated using CST Studio Suite operated within 37 to 39 GHz resonant frequency. The 2×2 MIMO antenna provides the most optimum results with bandwidth impedance of 1.783 GHz (4.7%) and achieve the reflection coefficient of −20 dB at 38 GHz application. The efficiency of the presented antenna has successfully achieved more than 80% with high gain of more than 7dBi. The presented antenna could be potential for point to point wireless base station terminal system.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131226617","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 objectives are to simulate and analyze the performances changes when the parameters of PCC are varied. THz PCC substrate microstrip antenna is a most simple way to generate the THz frequency. However, they are limited studies that have been done in terms of its fundamental physical analysis. Therefore, this analysis is proposed. Rectangular microstrip patch antenna on 2-D photonic crystal was simulated using electromagnetic simulation CAD Package.

With the use of software-defined radio base stations, costs of traditional base stations have been drastically reduced. However, operation of a base station still requires ownership of the licensed cellular band. In this paper, we present our implementation of a GSM network operating in the public utility frequency band (380MHz-400MHz) of the Philippines. A mobile adapter is implemented and attached to mobile phones allowing phones to communicate with the base station. The mobile adapter utilizes direct frequency translation to convert the licensed GSM signal of mobile phones to the 380MHz–400MHz frequency band. An implementation of a software-defined base station demonstrated that mobile phones can connect to the network by attaching the mobile adapter. The mobile adapter is foreseen to remove the costly license barrier to operation of local cellular operators by advantageously using both unused and underutilized frequencies, allowing more communities to set up their own networks and gain access to cellular connectivity.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123486784","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}
