Abstract
A new tri-band monopole antenna is proposed in this thesis. The antenna is made up of two simple L-shaped structures making it easy to fabricate and low in cost. The three target ISM bands (915MHz, 2.4GHz and 5.8GHz) enable it to be used for for low-power and short range telecommunications, such as WiFi, Bluetooth, Zigbee, wireless telephones, RFID, and NFC links. The bandwidths are designed to be in excess of the allotted bands making the antenna resistant to the presence of nearby object variations. This allows the antenna design to be used across the broadest possible application space. The proposed antenna is fabricated on an 80mm * 80mm RO4730 board and achieves a bandwidth of 9.3%, 66.7% and 12.4% at 915MHz, 2.4GHz, and 5.8GHz respectively. For the antenna gain, it achieves 2.5dBi, 4dBi and 4.3dBi at 915MHz, 2.4GHz and 5.8GHz respectively.
