In modern wireless communication system design, antennas with wide impedance bandwidth are desirable for numerous reasons. An antenna with a wide impedance bandwidth may be used for transmission and reception of multiple narrowband services in a multi-purpose platform. Alternatively a single wideband service may be of interest for various radar and imaging applications, or for impulse based radio...
The bandwidths of two aperture stacked patch antennas have been combined successfully into a single large bandwidth using microwave photonic techniques. The antenna system produces a 10 dB return loss bandwidth of approximately 105 % with average gain level of 5 dBi and amplitude variation of plusmn1.5 dB. Radiation analysis shows the level of interaction of the two antennas according to their relative...
This paper presents a demonstration an ultra-broadband photonic antenna. The antenna utilizes external optical intensity modulators and optic fiber to photonically remotes the aperture stacked patch antennas and replaces microwave diplexers with simple photonic combination. The resulting photonic antenna is demonstrated to provide a bandwidth of 110% with gain of 7 dBi
