Design of Dual Frequency Dual Linear Polarization Microstrip Patch Antenna

In today's latest communication technology, antennas play a most important role to create a communication link between transmitter & Receiver. Microstrip antennas are the most useful for mobile communication & Space communication applications because of their small size, light weight and lower power handling capacity. There are various shapes of microstrip antenna which improves the gain and bandwidth. In this paper, an innovative design of dual frequency dual linear polarization rectangular microstrip patch antenna is investigated. Dual linear polarized antennas offer low output correlation and high diversity gain. In this antenna design The Rogers RO3003 material of dielectric constant 3 has been used as the substrate of the antenna. Investigation is carried out related to bandwidth, gain and directivity the proposed antenna exhibits wide percentage bandwidth of approximately 2.49% at 2GHz and 4.99% at 3 GHz.
