From the detailed experimental study it is concluded that, by using orthogonal cross slot in CRMA i.e., OCSRMA makes the antenna to resonate for hexaband of frequencies and gives a peak gain of 2.02dB. This paper presents the novel design and development of orthogonal cross slot loaded rectangular microstrip antenna for multiband operation. The multibands are achieved by incorporating orthogonal slot of equal length at optimum place on the conducting patch. By adding two vertical slots on the patch the impedance bandwidth is enhanced in the upper operating band retaining the nature of broadside radiation characteristics. The proposed antenna may find application in radar communication.
