We have designed eLoran E/H-field antennas for hybrid integrated receiver. E-field and H-field antennas apply to eLoran receiver which uses for 100kHz long wavelength signal. Those antennas contain a RF amplifier with over 30dB gain and a filter to remove noise incoming from the antenna. There are two choices for antenna types: a dipole antenna that is responsive to the electric field (an E-field antenna) or a loop antenna that is responsive to the magnetic field (H-field antenna). The loop antenna should be combined with dual loops which are oriented 90 degrees to each other to achieve an omni-directional pattern because single loop has no omni-directional pattern.
