| Abstract | A low-profile microstrip patch antenna (MPA) operating in triple WLAN bands (2.4 /5.2 /5.8 GHz) with stable broadside radiation is proposed by employing TM10, TM12, and TM30 modes. Firstly, the TM12 mode of the MPA could be excited at around 5.8 GHz by properly selecting its dimensions. Meanwhile, a linear slot is etched out at the center of the radiating patch to transform the radiated fields of TM12 and TM30 modes into the broadside radiation with low sidelobe level. Secondly, the shorting pins are symmetrically loaded underneath the patch, aiming to improve the input impedance matching of TM10 mode and push up its resonant frequency to around 2.4 GHz. Thirdly, a pair of parallel slots is near the radiating edges of the patch radiator, thus extending the surface current distribution of TM30 mode and reallocating its resonant frequency to around 5.2 GHz. In final, the prototype antenna is fabricated and measured to validate its working principle. The results illustrate that this low-profile MPA makes these three radiative modes resonate at around 2.44, 5.22, and 5.82 GHz, respectively. Most importantly, a stable normal radiation pattern with low cross-polarisation and sidelobe levels is maintained for the proposed antenna as well. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
