Abstract
This paper studies a unique approach to combine coaxial periodic leaky wave (CPLW) antennas in parallel array configuration for restricted volume application. An improved gain and mitigated stopband attenuation are observed when up to four 200 mm long CPLW semi-rigid cables are simultaneously fed, forming a narrow beam pattern suitable for use in a confined volume due to the reduced size. The proposed antenna array exhibits a gain of greater than 10 dB from 8.0 to 10.5 GHz. The sidelobe levels are less than -10 dB at broadside frequency 9.8 GHz. The beam width of the CPLWA array is approximately 9° with a scanning range of greater than 25° over the operated frequency band. The array of CPLW antenna called parallel CPLWA array is discussed, fabricated and measured showing good agreement with simulations.
