Low Profile Antennas for the 435- MHz Band

 

 

Commentary by UR0GT: The Antenna Shaiba is a modification of the well- known Stub Dipole Antenna invented by Aleksandr Pistolkors in 1936. The lambda /4 Stub Dipole Antenna has input impedance 150- Ohm. (Note by I.G.: For example, the antenna is described at: Constantine A. Balanis: Antenna-Theory-Analysis-and-Design-Third Edition).

 

Because of the form the Antenna Shaiba has input impedance of 50-Ohm. Gain of the Antenna Shaiba less compare to lambda/4 vertical antenna (or vertical lambda /4 Stub Dipole Antenna). File MMANA gives answer what the Antenna Shaiba is. File MMANA for the Antenna Shaiba (designed for the 435- MHz Band) may be downloaded from: http://www.antentop.org/015/low_profile_antennas_015

 

Figure 2 shows design of the Antenna Shaiba for the 435- MHz Band accordingly to the MMANA file. Figure 3 shows Z of the Antenna Shaiba for the 435- MHz Band. Figure 4 shows SWR of the Antenna Shaiba for the 435- MHz Band. Figure 5 shows DD of the Antenna Shaiba for the 435- MHz Band.
