A novel printed circular antenna array based on V-shaped elements

A printed circular antenna array based on a V-shaped antenna element is designed and fabricated. The antenna array consisted of 8 elements, had a radius of 100 mm and was fabricated on a 0.8 mm FR-4 substrate. The array operated in the 2.5 GHz band with an approximate bandwidth of 150 MHz. A parametric sweep on the V-shaped antenna parameters was performed to understand the effect of each on the antenna resonance frequency and operating bandwidth. The array is to be used in direction finding applications. Good Correlation was obtained between simulated and measured results.
