Meander Line Base Asymmetric Co-planar Wave Guide (CPW) Feed Tri-Mode Antenna for Wi-MAX, North American Public Safety and Satellite Applications

This work states triband meander line base antenna with asymmetric Co-planar wave guide feed applicable for Wi-MAX, North American Public safety and Satellite Applications across the operating frequency of (5.3 GHz, 6.6 GHz, and 8.1 GHz). The proposed antenna with a compact size of 25 × 25 × 1.6 mm 3 is designed using Ansys electronics desktop software over an FR-4 epoxy substrate. Coplanar Wave guide (CPW) is printed on either side of the antenna to the meander-type patch. To minimize the S-parameters of the antenna, slots are placed in the CPW. The antenna performance was evaluated based on return loss, operational bandwidth, gain, VSWR and radiation pattern characteristics. During measurement, return loss was measured by reading the S(1,1) port reflection constant parameter, which was found to be < −10 dB. As a result, the proposed antenna shows an efficiency value of > 80% across the operating frequency. The presented antenna results are analyzed experimentally through ANRITSU-MS2037C combinational analyzer. It is observed that the measured results are confirmed with the simulated results.
