The longest element is active at the antenna’s lowest usable frequency where it acts as a half wave dipole. It is considered as a very popular form of a dipole antenna and is sometimes known as Hertz antenna.. Generally, it is known to be the one with the simplest resonance structure in antennas for the transmission and receptions applications. The antenna structure is fed by a modified microstrip feedline for better impedance matching. Z s = 363 – j (211) Ω. The most common dipole antenna is a half-wave dipole which is a piece of wire or rod which is one half wavelength in length. A pair of folded dipole antennas with a L- shape microstrip line is used to achieve wider bandwidth and better input port isolation. A biconical antenna has a broad frequency range that varies from 20 MHz to 18 GHz. It also depicts folded dipole antenna. In this situation, it's a good idea to make the antenna resonant at the lowest frequen- cy you plan to use it on (that's where the antenna is longest, because antenna length is proportional to wavelength). One of the most common applications of the dipole antenna is the rabbit ears or bunny ears television antenna, found atop broadcast television receivers. The far-field intensity \( \overline{\mathrm{P}}(\mathrm{r}, \theta)\) [W m-2] radiated by any antenna is a function of direction, as given for a short dipole antenna by (10.2.27) and illustrated in Figure 10.2.4.
