The phrase "a separate antenna" is correct and usable in written English.
It can be used when referring to an antenna that is distinct or independent from others, often in technical or communication contexts.
Example: "To improve signal reception, we decided to install a separate antenna on the roof."
Alternatives: "an additional antenna" or "a distinct antenna".
In a throwback to the early days of satellite TV, subscribers can only get them by using a separate antenna or through cable TV.
If there is an unwanted signal mixed up with the cosmic emissions observed by the radio telescope, the strategy is to record the terrestrial interference with a separate antenna, then try to subtract that signal to leave only the signal from space.
Actually, make that plural antennas since the each side of the iPhone is a separate antenna: one for Bluetooth, wi-fi and GPS positioning, the other for telephony.
Recently, Ngo et al. proposed the loop interference cancellation technique in a separate-antenna relay system, where the SI can be suppressed with a large-scale antenna linear processing (LALP) method in a random reflected-path SI environment [26].
In this paper, we present a complete UWB channel model that not only considers on-body UWB propagation but also extends to include LOS and NLOS channel measurement, using a TX antenna placed on the human body and a separate RX antenna located externally.
The BS is equipped with a separate massive antenna array.
Due to the separate antenna configuration at the BS; therefore, the reciprocity of uplink and downlink channels does not hold.
The wakeup radio can use its own separate antenna or share it with the main radio of the device.
Finally, we show that the SE PA can make the multi-user FD massive MIMO system outperform the HD counterpart no matter how big β LI is. 1 Due to the separate antenna configuration at the BS, therefore, the reciprocity of uplink and downlink channels does not hold.
To prepare analysis of the SIR conditions in the OFDM-SDMA system, we focus in this section on a separate single-antenna OFDM link.
Linear antennas are introduced and integrated on the bridge legs, which results in increased areas of the original spiral-type antennas on the support layer. Figure 1c e shows spiral-type antennas with a single separate linear antenna, two separate linear antennas, and two connected linear antennas on the bridge legs, respectively.
