- Description
- Microstrip antenna exhibiting low-profle features such as and#64258;exible, lightweight and newlinelow production cost attracts majority of communication industries working the lower newlinepart of the microwave spectrum ranging from 1 GHz to 6 GHz. Also, the microwave integrated circuit technology enables the integration of feed systems and other microwave integrated circuits on the same substrate where the antenna is printed. However, single antenna topologies feature a number of drawbacks, including low gain, poor directivity, narrow bandwidth and limited coverage being low in profle. In the perspective of miniaturization, developments in wireless communication have had a signifcant impact on antenna or array design based on the gain, bandwidth and directivity requirements for specifc wireless applications. As a result, usage of single antenna is not considered appropriate for diversity reception, long-distance communication, signal-to-interference as well as signal-to-noise ratio maximization, and direction of arrival determination, interference rejection, and high power applications. A high-gain broadband antenna or array may be the good choice for outdoor line-of-sight access points to increase signal strength and coverage range. To meet these requirements the antenna designers either can use conventional antennas or rely on miniaturized antennas. When antenna arrays are built using such small antennas to enhance the above said parameters, suitable and compact feed networks are required to ft within the given space of the overall transmitter-receiver geometry. This research work addresses the challenges faced by antenna researchers in newlineminiaturization, maintenance of gain-bandwidth and high-directivity narrow-beam newlineradiation of microstrip antenna arrays, through an investigation made on the design, new mathematical modelling of feed mechanisms for arrays, their inand#64258;uence on 1D and 2D uniform and non-uniform arrays, and the performance enhancement by amalgamating proposed arrays with defected ground structures and metasurfaces.
