The first one is a meandered loop antenna. Being in a meandered form, it can be made very compact. However, the gain and efficiency are quite low. In our study, the achieved gain is only -30dBi. Therefore, this configuration is not practical in use. We then studied a bow-tie antenna. Bow-tie antenna is typically considered to be a wide-band antenna. It takes more space than the loop antenna. Although the gain is increased up to 1.85dBi, the measured bandwidth of around 8% is less than what is required in DAB reception. The last one understudy is a dipole-patch antenna. This antenna is constructed by roughly half-sizing the previous bow-tie antenna. Measured -10db return loss bandwidth of the third antenna ranges from 192 to 236 MHz, or 21% bandwidth centered at 214MHz. The gain is 1.78dBi within the whole interested band. The third antenna is generally accepted for DAB reception. Advisor Committee The-nan Chang - advisor
