A shorted pin circular axe-shaped antenna is analyzed for compact and dual band applications. Removing two symmetric arc-shaped areas from a simple circular patch lengthens the current path thus reduces the antenna size. Embedding and adjusting a shorting pin further shifts the resonance to a lower frequency and excites another high order mode. The frequency ratio varies between 1.639 ∼ 2.616. The patch size is about 51% of the circular axe-shaped patch without shorting pin, and 85% of the simple circular patch antenna. Parametric analyses of the antenna model are presented in detail and a prototype is fabricated for experiment.
