Analysis of Plus Shape Slot Loaded Circular Microstrip Antenna
This paper presents the analysis of plus shape slot loaded patch antenna. It is observed that wideband property of antenna is found by suitably selecting the positions and dimensions of the slot on the patch. The operating frequency band of the proposed antenna is achieved from 6.60 to 8.15 GHz with bandwidth of 21.01% (simulated) and 6.50–8.33 GHz with 24.67% bandwidth (theoretical). The characteristics of the antenna are also observed by varying parameters like slot width, substrate height, and dielectric constant. The gain of the antenna is about 6.5 dBi in the operating frequency range. The simulated and theoretical results are compared which are in good agreement. The proposed antenna can be used in C-band applications.
