Abstract :
Insects posses garden variety of traits, but for some who lack the ability of vision, their species would have been extinct long ago. Through ingenuity of creation, these species adapted to the environment by developing antennas where they can use the basic principles of wave-propagation to feel the surrounding objects. In this paper a new design for broadband microstrip antennas was investigated. The main aim is to make the patch like a cockroach antenna. The antenna has shown to yield percentage bandwidth about 120% for a substrate with permittivity of 4.5. For using air substrate the antenna was fabricated and the percentage bandwidth was 42%. Furthermore some modifications were made to increase the bandwidth of air substrate antennas until it successfully reached 114%.
