    摘要： A microstrip antenna is formed of a 3.times.2 group of elements, with adjacent H-feeds. The outer pairs of elements are responsive to opposite senses of polarisation respectively and the inner pair of elements is responsive to both sense of polarisation. The appropriate phase for the respective element orientations are obtained by making S=r+.lambda./4 and q=p+.lambda./2 where .lambda. is the wavelength of radiation. The element spacing lies between 0.5.lambda. and 1.0.lambda., typically 0.85.lambda..Larger arrays are formed both by increasing the number of pairs of elements responsive to both senses of polarisation, but leaving the two outer pairs responsive only to respective opposite senses of polarisation, and by increasing the number of rows of pairs.

    摘要： A proximity fuzing arrangement for fuzing warheads carried by missiles which reduces the likelihood of the missile being detonated prematurely by such cases as rain or enemy counter measures. The fuzing arrangement includes at least two channels responsive to target signals in different frequency bands and also includes means for comparing the signals in these channels to distinguish between spurious signals such as enemy counter measures or rain and so called “true target signals”.
