The ZA-048 is a printed LDPA (Log-Periodic Dipole Array Antenna). Optimized design techniques significantly reduce its size, making it compatible with the tinySA ULTRA spectrum analyzer. Using new technology, it covers 400MHz-8GHz in a 27x23cm size, with some low-frequency directionality loss
The antenna's input resistance is rated at 50Ω, and return loss fluctuates when the antenna is connected to a 50Ω source. In most frequency bands above 1GHz, the return loss is about 10dB or less, and the VSWR is about 2. In the 400M-1GHz band, the return loss is about 4.5dB or less, and the VSWR is about 4. The VSWR increases rapidly at frequencies below 400MHz
ZA048 log-periodic dipole array antenna can be used for radio direction finding under the frequency between 1GHz-8.5GHz without strict requirements. It exerts a decent sensitivity of direction of the signal source when being held single-handedly and changes directions along with the body
Due to antenna area constraints, some low - frequency directionality was sacrificed. Please refer to the gain and front-back comparison charts below
